Equalizer Control Inputs
Diagnostic Mode Operation
Transmit All Ones
In Transmit All Ones (TAOS) mode, the TPOS and TNEG inputs to the transceiver are ignored.
The transceiver transmits a continuous stream of ones. TAOS can be commanded simultaneously
with Local Loopback, but is inhibited during Remote Loopback.
Remote Loopback
In Remote Loopback (RLOOP) mode, the transmit data and clock inputs (TPOS, TNEG and
TCLK) are ignored. The RPOS and RNEG outputs are looped back through the transmit circuits
and output on TTIP and TRING at the RCLK frequency. Receiver circuits are unaffected by the
RLOOP command and continue to output the RPOS, RNEG and RCLK signals received from the
twisted-pair line.
Local Loopback
In Local Loopback (LLOOP) mode, the receiver circuits are inhibited. The transmit data and clock
inputs (TPOS, TNEG and TCLK) are looped back onto the receive data and clock outputs (RPOS,
RNEG and RCLK) through the receive jitter attenuator. The transmitter circuits are unaffected by
the LLOOP command. The TPOS and TNEG inputs (or a stream of ones if the TAOS command is
active) will be transmitted normally.
LXT300Z Only: When used in this mode with a crystal, the transceiver can be used as a stand-alone
jitter attenuator.
