4.2.2. Single 10 Gbps PMA Direct Channel (without FEC)

Table 55.  Single 10 Gbps PMA Direct Channel Configuration
Data Rate TX and RX Double Width PMA Interface Core Interface tx_clkout Clock Source
10.3125 Gbps Enabled 20 bits 40 bits Half-Rate

For Core Interface FIFO in Phase Compensation mode, connect half rate tx_clkout (257.8125 MHz) to tx_coreclkin and connect rx_clkout (257.8125 MHz) to rx_coreclkin. If you use any other source for tx_coreclkin/rx_coreclkin, make sure tx_coreclkin and rx_coreclkin have 0 PPM difference with tx_clkout and rx_clkout, respectively. E-Tile FIFOs in this mode are used in REGISTER mode.
