Local Loopback (See Figure 9 and Figure 10)
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.
