Cyclone V Device Datasheet

This datasheet describes the electrical characteristics, switching characteristics, configuration specifications, and I/O timing for Cyclone^® V devices.

Cyclone^® V devices are offered in commercial and industrial grades. Commercial devices are offered in –C6 (fastest), –C7, and –C8 speed grades. Industrial grade devices are offered in the –I7 speed grade. Automotive devices are offered in the –A7 speed grade.

Cyclone^® V SoC devices are also offered in a low-power variant, as indicated by the L power option in the device part number. These devices have 30% static power reduction for devices with 25K LE and 40K LE, and 20% static power reduction for devices with 85K LE and 110K LE. Note that the L power option devices are only available in –I7 speed grade, and have the equivalent operating conditions and timing specifications as the standard –I7 speed grade devices.

To estimate total power consumption for a low-power device, listed in Table 1:

Multiply the Total Static Power reported by the Early Power Estimator (EPE) by the appropriate scale factor:
- For 25K LE and 40K LE devices, use 0.7
- For 85K LE and 110K LE devices, use 0.8
Add the result from Step 1 to the Total Dynamic Power reported by the EPE.

Maximum Allowed Overshoot and Undershoot Voltage

During transitions, input signals may overshoot to the voltage listed in the following table and undershoot to –2.0 V for input currents less than 100 mA and periods shorter than 20 ns.

The maximum allowed overshoot duration is specified as a percentage of high time over the lifetime of the device. A DC signal is equivalent to 100% duty cycle.

For example, a signal that overshoots to 4.00 V can only be at 4.00 V for ~15% over the lifetime of the device; for a device lifetime of 10 years, this amounts to 1.5 years.

Table 3. Maximum Allowed Overshoot During Transitions for Cyclone^® V DevicesThis table lists the maximum allowed input overshoot voltage and the duration of the overshoot voltage as a percentage of device lifetime.
Symbol	Description	Condition (V)	Overshoot Duration as % of High Time	Unit

		4.45	1.1	%
		4.5	0.6	%
		4.55	0.4	%
		4.6	0.2	%

For an overshoot of 3.8 V, the percentage of high time for the overshoot can be as high as 100% over a 10-year period. Percentage of high time is calculated as ([delta T]/T) × 100. This 10-year period assumes that the device is always turned on with 100% I/O toggle rate and 50% duty cycle signal.

DC Characteristics

Supply Current and Power Consumption

Intel offers two ways to estimate power for your design—the Excel-based Early Power Estimator (EPE) and the Intel^® Quartus^® Prime Power Analyzer feature.

Use the Excel-based EPE before you start your design to estimate the supply current for your design. The EPE provides a magnitude estimate of the device power because these currents vary greatly with the resources you use.

The Intel^® Quartus^® Prime Power Analyzer provides better quality estimates based on the specifics of the design after you complete place-and-route. The Power Analyzer can apply a combination of user-entered, simulation-derived, and estimated signal activities that, when combined with detailed circuit models, yields very accurate power estimates.

For more information about the maximum full duplex channels recommended in Cyclone^® V GT and ST devices for CPRI 6.144 Gbps, refer to the Transceiver Protocol Configurations in Cyclone^® V Devices chapter.

³⁶ The transmitter REFCLK phase jitter is 30 ps p-p at bit error rate (BER) 10^-12.

³⁷ The maximum supported clock frequency is 100 MHz if the PCIe* hard IP block is enabled or 125 MHz if the PCIe* hard IP block is not enabled.

³⁸ To support data rates lower than the minimum specification through oversampling, use the CDR in LTR mode only.

³⁹ The device cannot tolerate prolonged operation at this absolute maximum.

⁴⁰ The differential eye opening specification at the receiver input pins assumes that you have disabled the Receiver Equalization feature. If you enable the Receiver Equalization feature, the receiver circuitry can tolerate a lower minimum eye opening, depending on the equalization level.

⁴¹ The AC coupled V_ICM = 650 mV for Cyclone^® V GX and SX in PCIe* mode only. The AC coupled V_ICM = 750mV for Cyclone^® V GT and ST in PCIe* mode only.

⁴² t_LTR is the time required for the receive clock data recovery (CDR) to lock to the input reference clock frequency after coming out of reset.

⁴³ t_LTD is time required for the receiver CDR to start recovering valid data after the rx_is_lockedtodata signal goes high.

⁴⁴ t_{LTD_manual} is the time required for the receiver CDR to start recovering valid data after the rx_is_lockedtodata signal goes high when the CDR is functioning in the manual mode.

⁴⁵ t_{LTR_LTD_manual} is the time the receiver CDR must be kept in lock to reference (LTR) mode after the rx_is_lockedtoref signal goes high when the CDR is functioning in the manual mode.

⁴⁶ The rate matcher supports only up to ±300 parts per million (ppm).

⁴⁷ The Intel^® Quartus^® Prime software allows AC gain setting = 3 for design with data rate between 614 Mbps and 1.25 Gbps only.

Transmitter Pre-Emphasis Levels

The following table lists the simulation data on the transmitter pre-emphasis levels in dB for the first post tap under the following conditions:

Low-frequency data pattern—five 1s and five 0s
Data rate—2.5 Gbps

The levels listed are a representation of possible pre-emphasis levels under the specified conditions only and the pre-emphasis levels may change with data pattern and data rate.

Cyclone^® V devices only support 1st post tap pre-emphasis with the following conditions:

The 1st post tap pre-emphasis settings must satisfy |B| + |C| ≤ 60 where |B| = V_OD setting with termination value, R_TERM = 100 Ω and |C| = 1st post tap pre-emphasis setting.
|B| – |C| > 5 for data rates < 5 Gbps and |B| – |C| > 8.25 for data rates > 5 Gbps.
(V_MAX/V_MIN – 1)% < 600%, where V_MAX = |B| + |C| and V_MIN = |B| – |C|.

Exceptions for PCIe* Gen2 design:

V_OD setting = 50 and pre-emphasis setting = 22 are allowed for PCIe* Gen2 design with transmit de-emphasis –6dB setting (pipe_txdeemp = 1’b0) using Intel^® PCIe* Hard IP and PIPE IP cores.
V_OD setting = 50 and pre-emphasis setting = 12 are allowed for PCIe* Gen2 design with transmit de-emphasis –3.5dB setting (pipe_txdeemp = 1’b1) using Intel^® PCIe* Hard IP and PIPE IP cores.

For example, when V_OD = 800 mV, the corresponding V_OD value setting is 40. The following conditions show that the 1st post tap pre-emphasis setting = 2 is valid:

|B| + |C| ≤ 60→ 40 + 2 = 42
|B| – |C| > 5→ 40 – 2 = 38
(V_MAX/V_MIN – 1)% < 600%→ (42/38 – 1)% = 10.52%

To predict the pre-emphasis level for your specific data rate and pattern, run simulations using the Cyclone^® V HSSI HSPICE models.

⁵⁴ This specification is limited by the lower of the two: I/O f_MAX or F_OUT of the PLL.

⁵⁵ High bandwidth PLL settings are not supported in external feedback mode.

⁵⁶ A high input jitter directly affects the PLL output jitter. To have low PLL output clock jitter, you must provide a clean clock source with jitter < 120 ps.

⁵⁷ F_REF is f_IN/N, specification applies when N = 1.

⁵⁸ Peak-to-peak jitter with a probability level of 10^–12 (14 sigma, 99.99999999974404% confidence level). The output jitter specification applies to the intrinsic jitter of the PLL, when an input jitter of 30 ps is applied. The external memory interface clock output jitter specifications use a different measurement method and are available in Memory Output Clock Jitter Specification for Cyclone^® V Devices table.

⁵⁹ This specification only covers fractional PLL for low bandwidth. The f_VCO for fractional value range 0.20–0.80 must be ≥ 1200 MHz.

⁶⁰ External memory interface clock output jitter specifications use a different measurement method, which are available in Memory Output Clock Jitter Specification for Cyclone^® V Devices table.

⁶¹ This specification only covers fractional PLL for low bandwidth. The f_VCO for fractional value range 0.05–0.95 must be ≥ 1000 MHz.

⁶² The cascaded PLL specification is only applicable with the following conditions:

Upstream PLL: 0.59 MHz ≤ Upstream PLL BW < 1 MHz
Downstream PLL: Downstream PLL BW > 2 MHz

⁶³ Clock boost factor (W) is the ratio between the input data rate and the input clock rate.

⁶⁴ The F_max specification is based on the fast clock used for serial data. The interface F_max is also dependent on the parallel clock domain which is design dependent and requires timing analysis.

⁶⁵ The minimum specification depends on the clock source (for example, the PLL and clock pin) and the clock routing resource (global, regional, or local) that you use. The I/O differential buffer and input register do not have a minimum toggle rate.

⁶⁶ The maximum ideal data rate is the SERDES factor (J) × PLL max output frequency (f_out), provided you can close the design timing and the signal integrity simulation is clean. You can estimate the achievable maximum data rate by performing link timing closure analysis. You must consider the board skew margin, transmitter delay margin, and receiver sampling margin to determine the maximum data rate supported.

⁶⁷ You must calculate the leftover timing margin in the receiver by performing link timing closure analysis. You must consider the board skew margin, transmitter channel-to-channel skew, and receiver sampling margin to determine the leftover timing margin.

HPS PLL Input Clock Range

The HPS PLL input clock range is 10 – 50 MHz. This clock range applies to both HPS_CLK1 and HPS_CLK2 inputs.

HPS PLL Input Jitter

Use the following equation to determine the maximum input jitter (peak-to-peak) the HPS PLLs can tolerate. The divide value (N) is the value programmed into the denominator field of the VCO register for each PLL. The PLL input reference clock is divided by this value. The range of the denominator is 1 to 64.

Maximum input jitter = Input clock period × Divide value (N) × 0.02

⁶⁹ This value is based on rx_sample_dly = 1 and spi_m_clk = 120 MHz. spi_m_clk is the internal clock that is used by SPI Master to derive it’s SCLK_OUT. These timings are based on rx_sample_dly of 1. This delay can be adjusted as needed to accommodate slower response times from the slave. Note that a delay of 0 is not allowed. The setup time can be used as a reference starting point. It is very crucial to do a calibration to get the correct rx_sample_dly value because each SPI slave device may have different output delay and each application board may have different path delay. For more information about rx_sample_delay, refer to the SPI Controller chapter in the Hard Processor System Technical Reference Manual.

SD/MMC Timing Characteristics

Table 46. Secure Digital (SD)/MultiMediaCard (MMC) Timing Requirements for Cyclone^® V Devices
After power up or cold reset, the Boot ROM uses `drvsel` = 3 and `smplsel` = 0 to execute the code. At the same time, the SD/MMC controller enters the Identification Phase followed by the Data Phase. During this time, the value of interface output clock `SDMMC_CLK_OUT` changes from a maximum of 400 kHz (Identification Phase) up to a maximum of 12.5 MHz (Data Phase), depending on the internal reference clock `SDMMC_CLK` and the `CSEL` setting. The value of `SDMMC_CLK` is based on the external oscillator frequency and has a maximum value of 50 MHz.

After the Boot ROM code exits and control is passed to the preloader, software can adjust the value of `drvsel` and `smplsel` via the system manager. `drvsel` can be set from 1 to 7 and `smplsel` can be set from 0 to 7. While the preloader is executing, the values for `SDMMC_CLK` and `SDMMC_CLK_OUT` increase to a maximum of 200 MHz and 50 MHz respectively.

FPP Configuration Timing

DCLK-to-DATA[] Ratio (r) for FPP Configuration

Fast passive parallel (FPP) configuration requires a different DCLK-to-DATA[] ratio when you turn on encryption or the compression feature.

Depending on the DCLK-to-DATA[] ratio, the host must send a DCLK frequency that is r times the DATA[] rate in byte per second (Bps) or word per second (Wps). For example, in FPP ×16 where the r is 2, the DCLK frequency must be 2 times the DATA[] rate in Wps.

Cyclone^® V devices use additional clock cycles to decrypt and decompress the configuration data. If the DCLK-to-DATA[] ratio is greater than 1, at the end of configuration, you can only stop the DCLK (DCLK-to-DATA[] ratio – 1) clock cycles after the last data is latched into the Cyclone^® V device.

I/O Timing

Intel offers two ways to determine I/O timing—the Excel-based I/O timing and the Intel^® Quartus^® Prime Timing Analyzer.

Excel-based I/O timing provides pin timing performance for each device density and speed grade. The data is typically used prior to designing the FPGA to get an estimate of the timing budget as part of the link timing analysis.

The Intel^® Quartus^® Prime Timing Analyzer provides a more accurate and precise I/O timing data based on the specifics of the design after you complete place-and-route.
