4.8.3.1. 10G PCS Receiver and Transmitter Blocks

To implement a Native PHY link with the 10G PCS datapath, instantiate the Transceiver Native PHY IP in the IP Catalog, under Transceiver PHY in the Interfaces menu. When you select the 10G PCS option, a 10G PCS tab appears with the parameters and configuration options for each block.

The following blocks below can be enabled and disabled and configured in the 10G PCS.

  • Receive and Transmit FIFO
  • CRC32 Generator/Checker
  • Metaframe Generator/Synchronizer
  • 64B/66B Encoder/Decoder
  • Scrambler/Descrambler
  • Disparity Generator/Checker
  • Block Synchronizer
  • Multi-Gearbox

The hard PCS blocks natively support 10/40/100 Gigabit Ethernet and Interlaken. The remaining protocols are supported via 10G PCS Low Latency datapath configuration with the appropriate gearbox ratios.

10/40/100 Gigabit Ethernet Blocks Supported Configuration:

  • Receiver FIFO in Clock Compensation Mode and Transmit FIFO in Phase Compensation Mode
  • 64B/66B Encoder/Decoder
  • Scrambler/Descrambler
  • Block Synchronizer
  • 66:40 Gearbox Ratio

10/40/100 Gigabit Ethernet Blocks with 1588 Supported Configuration:

  • Receiver and Transmit FIFO in Registered Mode
  • 64B/66B Encoder/Decoder
  • Scrambler/Descrambler
  • Block Synchronizer
  • 66:40 Gearbox Ratio

Interlaken Blocks Supported Configuration:

  • Receiver and Transmit FIFO in Interlaken Elastic Buffer (Generic) Mode
  • CRC32 Generator/Checker
  • Metaframe Generator/Synchronizer
  • Scrambler/Descrambler
  • Disparity Generator/Checker
  • Block Synchronizer
  • 67:40 Gearbox Ratio

SFI-5.2 Blocks Supported Configuration:

  • Receiver and Transmit FIFO in Phase Compensation Mode
  • 64:64, 40:40, 64:32, and 32:32 Gearbox Ratios

10G SDI Blocks Supported Configuration:

  • Receiver and Transmit FIFO in Phase Compensation Mode
  • 50:40 Gearbox Ratio

Other Protocol Blocks Supported Configuration in Basic Mode:

  • Receiver and Transmit FIFO in Phase Compensation Mode
  • 64:64, 66:40, 40:40, 64:32, and 32:32 Gearbox Ratios
