2.2.5.1. PMA Interface Options

Table 23.  PMA Interface Options
Parameter Value Description
TX PMA interface width 16, 20, 32, 40, 64 Specifies the TX data interface width of the PMA. Refer to PMA Architecture for mapping the data widths to PMA mode.
RX PMA interface width 16, 20, 32, 40, 64 Specifies the RX data interface width of the PMA. Refer to PMA Architecture for mapping the data widths to PMA mode.
TX PMA interface FIFO mode

Phase Compensation

Elastic

Specifies the mode for the TX PMA Interface FIFO.
Enable TX PMA interface FIFO write when full On/Off Enables or disables the TX PMA interface FIFO write option when the FIFO is full.
Enable TX PMA interface FIFO read when empty On/Off Enables or disables the TX PMA interface FIFO read option when the FIFO is empty.
TX PMA interface FIFO almost empty threshold 7 Specifies the almost empty threshold for the TX PMA Interface FIFO.
TX PMA interface FIFO empty threshold 0 Specifies the empty threshold for the TX PMA Interface FIFO.
Enable tx_enh_pmaif_fifo_almost_full port On/Off Enables the port which indicates TX PMA Interface FIFO's almost full condition.
Enable tx_enh_pmaif_fifo_almost_empty port On/Off Enables the port which indicates TX PMA Interface FIFO's almost empty condition.
Enable tx_enh_pmaif_fifo_overflow port On/Off Enables the port which indicates TX PMA Interface FIFO's overflow condition. The port/signal is sticky, so you must reset it.
Enable tx_enh_pmaif_fifo_underflow port On/Off Enables the port which indicates TX PMA Interface FIFO's underflow condition. The port/signal is sticky, so you must reset it.
Enable rx_pmaif_fifo_underflow port On/Off Enables the port which indicates RX PMA Interface FIFO's underflow condition. The port/signal is sticky, so you must reset it.
Enable rx_enh_pmaif_fifo_overflow port On/Off Enables the port which indicates RX PMA Interface FIFO's overflow condition. The port/signal is sticky, so you must reset it.
