TAOS Data Path
Local Loopback
Local Loopback (LLOOP) is selected when LLOOP = 1 and RLOOP = 0. In LLOOP mode,
the receiver circuits are inhibited. The transmit clock and data inputs (TCLK and TPOS/
TNEG or TDATA) are looped back and output at RCLK and RPOS/RNEG or RDATA.
During Local Loopback, the JASEL input functions as follows: If JASEL = 0, JA is enabled
and active in both the Transmit path and the loopback circuit. If JASEL = 1, JA is enabled
in the Loopback circuit only. If JASEL = MCLK, JA is disabled.
The transmitter circuits are unaffected by LLOOP. The TPOS/TNEG or TDATA inputs (or a
stream of 1s if the TAOS command is active) will be transmitted normally. When used in
this mode, the transceiver can be used as a stand-alone jitter attenuator.
