Signal Name Direction Description
tx_pma_clkout
Output Clock used to drive the 10G TX PCS and 1G TX PCS parallel data. For
example, when the hard PCS is reconfigured to the 10G mode
without FEC enabled, the frequency is 257.81 MHz. The frequency is
161.13 MHz for 10G with FEC enabled.
rx_pma_clkout
Output Clock used to drive the 10G RX PCS and 1G RX PCS parallel data. For
example, when the hard PCS is reconfigured to the 10G mode
without FEC enabled, the frequency is 257.81 MHz. The frequency is
161.13 MHz for 10G with FEC enabled.
tx_clkout
Output XGMII/GMII TX clock for the TX parallel data source interface. This
clock frequency is 257.81 MHz in 10G mode, and 161.13 MHz with
FEC enabled.
rx_clkout
Output XGMII RX clock for the RX parallel data source interface. This clock
frequency is 257.81 in 10G mode, and 161.13 MHz with FEC
enabled.
tx_pma_div_clkout
Output The divided 33 clock from the TX serializer. You can use this clock for
the for xgmii_tx_clk or xgmii_rx_clk. The frequency is 156.25
MHz for 10G. The frequencies are the same whether or not you
enable FEC.
rx_pma_div_clkout
Output The divided 33 clock from CDR recovered clock. The frequency is
156.25 MHz for 10G. The frequencies are the same whether or not
you enable FEC. This clock is not used for clocking the 10G RX
datapath.
tx_analogreset
Input Resets the analog TX portion of the transceiver PHY. Synchronous to
mgmt_clk.
tx_digitalreset
Input Resets the digital TX portion of the transceiver PHY. Synchronous to
mgmt_clk.
rx_analogreset
Input Resets the analog RX portion of the transceiver PHY. Synchronous to
mgmt_clk.
rx_digitalreset
Input Resets the digital RX portion of the transceiver PHY. Synchronous to
mgmt_clk.
usr_seq_reset
Input Resets the sequencer. Initiates a PCS reconfiguration, and may
restart AN, LT or both if these modes are enabled. Synchronous to
mgmt_clk.

Input Synchronous to
xgmii_tx_clk
XGMII data and control for 8 lanes. Each lane consists of 8
bits of data and 1 bit of control.
xgmii_tx_clk
Input Clock signal Clock for single data rate (SDR) XGMII TX interface to the
MAC. It should connect to xgmii_rx_clk. This clock can be
connected to the tx_div_clkout; however, Intel
