E3/DS3/STS-1 LINE INTERFACE UNIT WITH SONET DESYNCHRONIZER

8.2.1
In this mode, the transmitter outputs (TTIP and TRING) are connected internally to the receiver inputs (RTIP
and RRING) as shown in Figure 26. Data and clock are output at RCLK, RPOS and RNEG pins for the
corresponding transceiver. Analog loopback exercises most of the functional blocks of the device including the
jitter attenuator which can be selected in either the transmit or receive path.
XRT75L00D can be configured in Analog Loopback either in Hardware mode via the LLB and RLB pins or in
Host mode via LLB and RLB bits in the channel control registers.

In the Analog loopback mode, data is also output via TTIP and TRING pins.
Signals on the RTIP and RRING pins are ignored during analog loopback.
8.2.2
The Digital Loopback function is available either in Hardware mode or Host mode. When the Digital Loopback
is selected, the transmit clock (TxClk) and transmit data inputs (TPDATA & TNDATA) are looped back and
output onto the RxClk, RPOS and RNEG pins as shown in Figure 27. The data presented on TxClk, TPDATA
and TNDATA are not output on the TTIP and TRING pins.This provides the capability to configure the
protection card (in redundancy applications) in Digital Loopback mode without affecting the traffic on the
primary card.
