5. Parameters

Table 18.   GTS Serial Lite IV Intel® FPGA IP Parameter Description
Parameter Value Default Description
General Design Options
PMA data rate 1 Gbps – 28.1 Gbps 10.3125 Gbps Specifies the effective data rate at the output of the transceiver incorporating transmission and other overheads. The value is calculated by the IP by rounding up to 1 decimal place in Gbps unit.
  • Supported rates for E-Series (Device Group B): 1 - 17.16 Gbps.
  • Supported rates for E-Series (Device Group A) and D-Series: 1 - 28.1 Gbps.
PMA mode
  • Duplex, Tx and Rx
Duplex The supported direction is duplex, Tx and Rx.
Number of PMA lanes 1 – 4 1 Select the number of lanes. The supported number of lanes is 1 – 4.
PMA reference clock frequency 100 MHz – 379.84375 MHz, depending on the selected transceiver data rate. 156.25 MHz Specifies the reference clock frequency of the transceiver.
System PLL reference clock frequency — 170 MHz Available when the System PLL frequency selection is set to Custom, regardless of the transceiver type.
System PLL frequency
  • N 10
  • Custom
322.265625 MHz Specifies the system PLL clock frequency.
Custom System PLL frequency — 322.265625 MHz Specifies custom system PLL frequency. This field is enabled when System PLL frequency is set to Custom.
Alignment Period 128 – 65536 128 Specifies the alignment marker period.

The value must be x2.

Enable RS-FEC

Enable

Disable

Disable Turn on to enable the RS-FEC (528, 514) feature.
User Interface
Streaming mode
  • FULL
  • BASIC
Full Select the data streaming for the IP.

FULL: This mode sends a start-of-packet and end-of-packet cycle within a frame.

BASIC: This is a pure streaming mode where data is sent without a start-of-packet, empty, and end-of-packet to increase bandwidth.

Enable CRC

Enable

Disable

Disable Turn on to enable CRC error detection and correction.
Enable auto alignment

Enable

Disable

Disable Turn on to enable automatic lane alignment feature.
Enable debug endpoint

Enable

Disable

Disable Turn on to enable debug endpoint for Transceiver Toolkit.
Simplex Merging (This parameter setting is only available when you set PMA mode as Tx or Rx.)
RS-FEC enabled on the other Serial Lite IV Simplex IP placed at the same channel(s)

Enable

Disable

Disable

Turn on this option if you require a mixture of configuration with RS-FEC enabled and disabled for the GTS Serial Lite IV Intel® FPGA IP in a dual simplex design, where both TX and RX are placed on the same channel(s).

10 This is a system-generated value based on the PMA data rate.
