188.8.131.52. PMA Features
PMA channels are comprised of transmitter (TX), receiver (RX), and high speed clocking resources.
The transmit features deliver exceptional signal integrity at data rates up to 58 Gbps PAM4 / 28.9 Gbps NRZ.
Each PMA also has advanced equalization circuits that compensate for transmission losses across a wide frequency spectrum.
|Data Rates||Up to 58 Gbps|
|Optical Module Support||
XFP, QSFP-DD, OSFP, QSFP/QSFP28, QSFP56, SFP+, SFP28, SFP56, CFP/CFP2/CFP4 optical module support
|Cable Driving Support||SFP+ Direct Attach, eSATA|
One post-tap and three pre-tap for PAM4
One post-tap and one pre-tap for NRZ
|Dynamic Reconfiguration||Allows for independent control of each transceiver channel Avalon memory-mapped interface for the most transceiver flexibility|
Multiple PCS-PMA and PCS-Core to FPGA fabric interface widths
16, 20, 32, 40 or 64 bit interface widths for flexibility of deserialization width, encoding and reduced latency
