5. Parameters

Table 22.   F-Tile Serial Lite IV Intel® FPGA IP Parameter Description
Parameter Value Default Description
General Design Options
PMA modulation type
  • PAM4
  • NRZ
PAM4 Select the PCS modulation mode.
PMA type
  • FHT
  • FGT
FGT Selects the transceiver type.
PMA data rate
  • For PAM4 mode:
    • FGT transceiver type: 20 Gbps – 58 Gbps
    • FHT transceiver type: 48 Gbps – 58 Gbps, 96 Gbps – 116 Gbps
  • For NRZ mode:
    • FGT transceiver type: 1 Gbps – 28.05 Gbps
    • FHT transceiver type: 24 Gbps – 29 Gbps, 48 Gbps – 58 Gbps

56.1 (FGT/FHT PAM4)

28.05 Gbps (FGT/FHT NRZ)

 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.
PMA mode
  • Duplex
  • Tx
  • Rx
Duplex For FHT transceiver type, the supported direction is duplex only. For FGT transceiver type, the supported direction is Duplex, Tx, and Rx.
Number of PMA lanes
  • For PAM4 mode:
    • FGT transceiver type: 1 to 12
    • FHT transceiver type: 1 to 4
  • For NRZ mode:
    • FGT transceiver type: 1 to 16
    • FHT transceiver type: 1 to 4
2 Select the number of lanes. For simplex design, the supported number of lanes is 1.
PMA reference clock frequency
  • For FHT transceiver type: 156.25 MHz
  • For FGT transceiver type: 27.5 MHz – 379.84375 MHz, depending on the selected transceiver data rate.
  • For FHT transceiver type: 156.25 MHz
  • For FGT transceiver type: 165 MHz
 Specifies the reference clock frequency of the transceiver.
System PLL reference clock frequency — 170 MHz Only available for FHT transceiver type. Specifies the system PLL reference clock and is used as input of F-Tile Reference and System PLL Clocks Intel FPGA IP to generate the system PLL clock.
System PLL frequency
  • N 9
  • Custom
876.5625 MHz Specifies the system PLL clock frequency.
Custom System PLL frequency — 876.5625 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

 Enable Turn on to enable the RS-FEC feature.

For PAM4 PCS modulation mode, RS-FEC is always enabled.
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 When ON, the F-Tile Serial Lite IV Intel® FPGA IP includes an embedded Debug Endpoint that internally connects to the Avalon® memory-mapped interface. The IP can perform certain tests and debug functions through JTAG using the System Console. Default value is Off.
Simplex Merging (This parameter setting is only available when you select FGT dual simplex design.)
RSFEC enabled on the other Serial Lite IV Simplex IP placed at the same FGT channel(s)

Enable

Disable

 Disable

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

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