4.1.6
The test breakout function provides the capability to multiplex one of the incoming 16
(28) receive links to the outgoing test receive port, that is the incoming receive clock
signal RCLK(x) is mapped to the test receive clock output TRCLK, the receive
synchronization pulse RSP(x) is mapped to TRSP (16-port mode only) and the incoming
receive data signal RD(x) is mapped to the test data output TRD. In the opposite
direction one of the 16 (28) transmit data output signals TD(x) can be replaced with the
test transmit data signal TTD. Furthermore the corresponding transmit synchronization
pulse input TSP(x) (16-port mode only) and the transmit clock input signal TCLK(x) can
be monitored on the test port outputs TTSP and TTCLK. There is no processing function
in the data path. Each output signal is a buffered version of the corresponding input
signal, e.g. output signal TD(x) is a buffered version of the incoming signal TTD.
