Description

rx_dataout_bp<n>

Input

When asserted, enables reading of data from the RX FIFO. This

signal functions as a read enable. The RX interface has a ready

latency of 1 cycle so that

rx_paralleldata<n>[63:0]

and

rx_

paralleldata<n>[65]

are valid the cycle after

rx_dataout_

bp<n>

is asserted.

In multi-lane configurations, the

rx_dataout_bp

port

signals must not be logically tied together.
This output is synchronous to the

rx_coreclkin

clock domain.

You can tie this

rx_dataout_bp<n>

RX FIFO read enable signal

to the inverted logic of the

rx_parallel_data[68]

RX FIFO

partially empty signal using the following assignment statement:

assign rx_dataout_bp[0] =! (rx_parallel_data[68]);

rx_user_clkout

Output

Master channel

rx_user_clkout

is available when you do not

create the optional

rx_coreclkin

.

Description

tx_serial_data

Output

Differential high speed serial output data using the

PCML I/O standard. Clock is embedded in the serial

data stream.

rx_serial_data

Input

Differential high speed serial input data using the

PCML I/O standard. Clock is recovered from the serial

data stream.
