rx_cdr_refclk[<n>-1:0]
Input Input reference clock for the RX PFD circuit.
Resets
pll_powerdown[<n>-1:0]
Input
When asserted, resets the TX PLL. Active high, edge sensitive
reset signal.
tx_analogreset[<n>-1:0]
Input
When asserted, resets for TX PMA, TX clock generation block,
and serializer. Active high, edge sensitive reset signal.
tx_digitalreset[<n>-1:0]
Input
When asserted, resets the digital components of the TX datapath.
Active high, edge sensitive reset signal.If your design includes
bonded TX PCS channels, refer to Timing Constraints for Reset
Signals when Using Bonded PCS Channels for a SDC constraint
you must include in your design.
rx_analogreset[<n>-1:0]
Input
When asserted, resets the RX CDR, deserializer, Active high, edge
sensitive reset signal.
rx_digitalreset[<n>-1:0]
Input
When asserted, resets the digital components of the RX datapath.
Active high, edge sensitive reset signal.
Parallel data ports
tx_pma_parallel_data[<n>80-1:0]
Input
TX parallel data for the PMA Direct datapath. Driven directly from
the FPGA fabric to the PMA. Not used when you enable either the
Standard or 10G PCS datapath.
rx_pma_parallel_data[<n>80-1:0]
Output
RX PMA parallel data driven from the PMA to the FPGA fabric.
Not used when you enable either the Standard or 10G PCS
datapath.
tx_parallel_data[<n>64-1:0]
Input
PCS TX parallel data. Used when you enable either the Standard
or 10G datapath. For the Standard datapath, if you turn on Enable
simplified data interface,
tx_parallel_data
includes only the
data and control signals necessary for the current configuration.
Dynamic reconfiguration of the interface is not supported.
For the 10G PCS, if the parallel data interface is less than 64 bits
wide, the low-order bits of
tx_parallel_data
are valid.
For the 10G PCS operating in 66:40 mode, the 66 bus is formed
as follows: {
tx_parallel_data[63:0],tx_10g_control[0],
tx_10g_control[1]}.
rx_parallel_data[<n>64-1:0]
Output
PCS RX parallel data. Used when you enable either the Standard
or 10G datapath. For the Standard datapath, if you turn on Enable
simplified data interface,
rx_parallel_data
includes only the
data and control signals necessary for the current configuration.
Dynamic reconfiguration of the interface is not supported.
For the 10G PCS, if the parallel data interface is less than 64 bits
wide, the low-order bits of
rx_parallel_data
are valid.
For the 10G PCS operating in 66:40 mode, the 66 bus is formed
as follows: {
rx_parallel_data[63:0],rx_10g_control[0],
rx_10g_control[1]}.
QPI
tx_pma_qpipullup
Input QPI control input port. Only for QPI applications.
tx_pma_qpipulldn
Input QPI control input port. Only for QPI applications.
