This pin must be pulled up through a 10-kΩ resistor to VCCIO_SDM for all configuration schemes. This pin has an internal 25-kΩ pull-up.

When you use the Avalon-ST configuration scheme, connect this pin directly to the configuration host.

When you use other configuration schemes, pull this pin to VCCIO_SDM through an external 10-KΩ pull-up resistor. When you use other configuration schemes, this pin can be used to restart configuration by driving it low and then high again.

You must provide an external clock source to this pin if you are using transceivers.

If you choose to use the external clock source for configuration and/or instantiate any transceivers in your design, you must provide a 25-MHz, 100-MHz, or 125-MHz free-running clock source to this pin and enable it in the Intel^® Quartus^® Prime software when you compile your design.

Dual-purpose fundamental reset pin that is only available when you use together with PCI Express^® (PCIe^®) hard IP (HIP).

When the PCIe HIP on a side (left or right) is enabled, the nPERST pins on that side cannot be used as general-purpose I/Os (GPIOs). In this case, connect the nPERST pin to the system PCIe nPERST signal to ensure that both ends of the link start link-training at the same time. The nPERST pins on a side are available as GPIOs only when the PCIe HIP on that side is not enabled.

When the pin is low, the transceivers are in reset. When the pin is high, the transceivers are out of reset. When you do not use this pin as the fundamental reset, you can use this pin as a user I/O pin.

Connect this pin as defined in the Intel^® Quartus^® Prime software. This pin is powered by the VCCIO3V supply.

When VCCIO3V is connected to a 3.0-V supply, you must use a diode to clamp the 3.3V LVTTL PCIe input signal to the VCCIO3V power of the device.

When VCCIO3V is connected to any voltage other than 3.0V, you must use a level translator to shift down the voltage from 3.3V LVTTL to the corresponding voltage level powering the VCCIO3V pin.

For maximum compatibility, always use the bottom left PCIe HIP first, as this is the only location that supports Configuration via Protocol (CvP) using the PCIe link.

See Note 13 in Notes to Intel^® Stratix^® 10 GX Pin Connection Guidelines.

These are the 3.0V I/O pins. Each transceiver tile supports eight 3.0V I/O pins. These pins support 1.2V, 1.25V, 1.35V, 1.5V, 1.8V, 2.5V, and 3.0V I/O standards.

VCCLSENSE and GNDSENSE are differential remote sense pins for the VCC power. Connect your regulators’ differential remote sense lines to the respective VCCLSENSE and GNDSENSE pins. This compensates for the DC IR drop associated with the PCB and device package from the VCC power. Route these connections as differential pair traces and keep them isolated from any other noise source.

You must connect the VCCLSENSE and GNDSENSE lines to the regulator’s remote sense inputs.

Analog power, receiver, specific to each transceiver bank of the left (L) side or right (R) side of the device.

Connect VCCR_GXB pins to a 1.03V or 1.12V low noise switching regulator depending on the transceiver data rate.

VCCR_GXB and VCCT_GXB pins of each bank within a transceiver tile (L-tile or H-tile) must have the same voltage (either 1.03V or 1.12V). However, VCCR_GXB and VCCT_GXB of different banks within the same transceiver tile can have different voltages based on the configured transceiver data rates to further reduce power consumption of the transceiver tile. When the banks within a transceiver tile are powered at different voltages (for example, some banks operating at 1.03V while other banks operating at 1.12V), the xN clock lines are only allowed to transverse between contiguous banks operating at the same VCCR_GXB or VCCT_GXB voltages. The xN clock lines crossing boundaries of banks operating at different voltages is not allowed. For any input reference clock coming into a transceiver tile, that clock can be distributed to any bank within the tile even if the VCCR_GXB and VCCT_GXB operating voltages of the banks are different.

When all of the transceivers on the same tile are not used, you may power down the transceivers in that tile by connecting its VCCR_GXB, VCCT_GXB, and VCCH_GXB to GND.

Place a 22-nF decoupling capacitor between each VCCR_GXB power pin and GND pin on the back side of the BGA pin field.

The VCCR_GXB and VCCT_GXB voltage supplies can vary depending on whether it is an L-tile or H-tile device as well as the channel configuration (non-bonded versus bonded channels) on each tile. For more information about the voltage requirement for your specific use case, refer to the Intel^® Stratix^® 10 Device Datasheet.

See Notes 2, 3, 4, 7, and 10 in Notes to Intel^® Stratix^® 10 GX Pin Connection Guidelines.

Connect VCCT_GXB pins to a 1.03V or 1.12V low noise switching regulator depending on the transceiver data rate.

VCCR_GXB and VCCT_GXB pins of each bank within a transceiver tile (L-tile or H-tile) must have the same voltage (either 1.03V or 1.12V). However, VCCR_GXB and VCCT_GXB of different banks within the same transceiver tile can have different voltages based on the configured transceiver data rates to further reduce power consumption of the transceiver tile.

The xN clock lines crossing boundaries of banks operating at different voltages is not allowed. For any input reference clock coming into a transceiver tile, that clock can be distributed to any bank within the tile even if the VCCR_GXB and VCCT_GXB operating voltages of the banks are different.

When all of the transceivers on the same tile are not used, you may power down the transceivers in that tile by connecting its VCCR_GXB, VCCT_GXB, and VCCH_GXB to GND.

Place a 22-nF decoupling capacitor between each VCCT_GXB power pin and GND pin on the back side of the BGA pin field.

The VCCR_GXB and VCCT_GXB voltage supplies can vary depending on whether it is an L-tile or H-tile device as well as the channel configuration (non-bonded versus bonded channels) on each tile.

See Notes 2, 3, 4, 7, and 10 in Notes to Intel^® Stratix^® 10 GX Pin Connection Guidelines.

Connect VCCH_GXB to 1.8V low noise switching regulator.

With a proper isolation filtering, you have the option to source VCCH_GXB from the same regulator as VCCPT.

To minimize the regulator switching noise impact on channel jitter performance, keep the switching frequency for VCCH_GXB regulator below 2 MHz. For OTN applications, the switching frequency for VCCH_GXB is recommended to be below 500 KHz.

Place a 22-nF decoupling capacitor between each VCCH_GXB power pin and GND pin on the back side of the BGA pin field.

A leakage voltage may be observed on the VCCH_GXB power rail before the VCCH_GXB is powered on due to leakage inside the device during the power-up and power-down sequencing. The total magnitude of this leakage voltage is lower than VCCH_GXB and this is an expected behavior.

During the power-up sequence only, a transient current whose magnitude is less than the VCCH_GXB static operating current may be observed. The floating voltage and transient current are expected behavior and will neither cause any functional failure nor reliability concerns to the device as long as the power-up or power-down sequence is followed.

When all of the transceivers on the same tile are not used, you may power down the transceivers in that tile by connecting its VCCR_GXB, VCCT_GXB, and VCCH_GXB to GND.

PMBus Power Management Clock.

By default, the PWRMGT_SCL function is enabled in SDM_IO14. If you use Avalon-ST x8 configuration scheme, you must implement this function using the SDM_IO0 pin.

This pin is pulled low internally by a 25-kΩ resistor when the device is powered up.

When this pin is used as the PWRMGT_SCL function, this pin requires a pull-up resistor to the 1.8V VCCIO_SDM supply. Intel recommends a pull-up value of 5.1-kΩ to 10-kΩ depending on the loading of this pin. Use the voltage level translators when interfacing to the PMBus interfaces requiring voltages other than 1.8V.

This pin is used as the clock pin for the PMBus interface.

When a –V device is used, you must enable the SmartVID connection between the device and the VCC voltage regulator to allow the FPGA to directly control its core voltage requirements. You can do this by connecting the PWRMGT_SCL and PWRMGT_SDA signals to the VCC voltage regulator for the PMBus master mode and the PWRMGT_SCL, PWRMGT_SDA, and PWRMGT_ALERT signals to the VCC voltage regulator for the PMBus slave mode.

Connect this pin to the PMBus clock pin of your regulator.

The INIT_DONE pin indicates the device has enter user mode upon completion of configuration. When used for this purpose, this pin must be enabled by the Intel^® Quartus^® Prime software.

Intel^® recommends you to use SDM_IO0 or SDM_IO16 to implement the INIT_DONE function when available as it has an internal weak pull-down for the correct function of INIT_DONE during power up.

If SDM_IO0 and SDM_IO16 are unavailable, SDM_IO5 can also be used for the INIT_DONE function when the configuration mode is set to Avalon^® –ST x8 or Avalon^® –ST x32 (AVST x8 or AVST x32) as these modes require an external 4.7–kΩ pull-down resistor.

If SDM_IO0, SDM_IO5, and SDM_IO16 are unavailable, the INIT_DONE function can also be implemented using any unused SDM I/O pins provided that an external 4.7–kΩ pull-down resistor is provided for the INIT_DONE signal.

This pin is pulled low internally by a 25-kΩ resistor when the device is powered up.

PMBus Power Management Alert.

When this pin is used as the PWRMGT_ALERT function, this pin requires a pull-up resistor to the 1.8V VCCIO_SDM supply.
