Table 45.  TX and RX Parallel and Serial Interface SignalsRefer to Variables Defining Bits for the Interfacing Ports in Port and Signal Reference for variable definitions.
Signal Name Clocks Domain/Resets Direction Description
tx_parallel_data [(80 * N * X)-1:0]

tx_coreclkin

tx_reset

input Parallel data bus from FPGA core to F-tile interface. Some bits map to specific functionality, as Parallel Data Mapping Information describes.

rx_coreclkin

rx_reset

output Parallel data bus from FPGA core to F-tile interface. Some bits map to specific functionality, as TX and RX Parallel Data Mapping Information for Different Configurations describes.
tx_serial_data [N-1:0] tx_reset output TX serial data port.
tx_serial_data_n [N-1:0] tx_reset output Differential pair for TX serial data port.
rx_serial_data [N-1:0] rx_reset input RX serial data port.
