Functional Description
XSBI uses 16-bit LVDS data to interface between the PCS and the PMA
sublayer.
Figure 8–4. XSBI Functional Block Diagram
On the transmitter side, the transmit data (TX_D[15..0]) is output by
the PCS and input at the PMA using the transmitter clock (PMA_TXCLK),
which is derived from the PMA source clock (PMA_TXCLK_SRC). The
PMA source clock is generated from the PMA with its reference clock
(REFCLK). On the receiver side, the receiver data (RX_D[15..0]) is
output by the PMA and input at the PCS using the PMA-generated
receiver clock (PMA_RXCLK). The SYNC_ERR optional signal is sent to the
PCS by the PMA if the PMA fails to recover the clock from the serial data
stream.
The ratios for these two clocks and data are dependent on the type of PHY
used.
