Table 16. 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.
Enable
tx_enh_pmaif_fifo
_underflow port
On/Off Enables the port which indicates TX PMA Interface FIFO's underflow condition.
Enable
rx_pmaif_fifo_und
erflow port
On/Off Enables the port which indicates RX PMA Interface FIFO's underflow condition.
Enable
rx_enh_pmaif_fifo
_overflow port
On/Off Enables the port which indicates RX PMA Interface FIFO's overflow condition.

2.2.5. PMA Adaptation
After power-on configuration, you may need to run calibration on the RX side to
achieve the best performance. There is initial adaptation for initialization calibration
and continuous adaptation which you can keep running in the background. In the
Native PHY IP, the PMA Adaptation tab is used for both initial and continuous
adaptation.
