10-Bit Mode (Coded Data)
Backplane 10-bit mode is enabled by asserting TBIE high and negating COMPAT low, as shown in
Received data is 10 bits of coded data. The internal 8B/10B decoder is bypassed. Receiver data is presented
on the signals: RECV_x_ERR, RECV_x_DV, and RECV_x_7–RECV_x_0 (making up bits 9–0,
respectively).
The RECV_x_COMMA is asserted high whenever the 10-bit code group is 1 of the 3 COMMA code
groups.
The RECV_x_K is asserted high when the receiver is in an error state. When RECV_x_K is high, the state
of the RECV_x_7–RECV_x_0 signals are decoded to determine the error condition.
The receiver interface is timed to the clock output, RECV_x_RCLK.

Not byte sync: The receiver is in start-up or
has lost byte alignment and is searching for
alignment.
1 The priority column shows the error that is reported if multiple errors occur at the same time. The lower priority-numbered errors
are reported first.
