OCTAL T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR

REV. 1.0.2

REMOTE LOOP-BACK (RLOOP)

With Remote Loop-Back activated, receive data after the jitter attenuator (if selected in the receive path) is

looped back to the transmit path using RCLK as transmit timing. In this mode transmit clock and data are

ignored, while RCLK and receive data will continue to be available at their respective output pins. Remote

Loop-Back with jitter attenuator selected in the receive path is shown in Figure 21.

In the Remote Loop-Back mode if the jitter attenuator is selected in the transmit path, the receive data from the

Clock and Data Recovery block is looped back to the transmit path and is applied to the jitter attenuator using

RCLK as transmit timing. In this mode the transmit clock and data are also ignored, while RCLK and received

data will continue to be available at their respective output pins. Remote Loop-Back with the jitter attenuator

selected in the transmit path is shown in Figure 22.
