2.5
The 4-bit LVDS 622/666MHz parallel output data of the receive path is used to interface to a SONET Framer/
ASIC synchronized to the recovered clock. A simplified block diagram is shown in Figure X.
Receive Parallel Output Interface
2.6
The receive parallel output data from the OC-48 receiver will adhere to the setup and hold times shown in
Figure 6 and Table 3.

The Receiver outputs can automatically be pulled "Low" during a LOS condition to prevent data chattering. By
pulling DISRD "High", the Receiver outputs will pull "Low" any time a LOS condition occurs.
2.8
Tri-State Receive Output Data
Unlike DISRD, TRIRXD is used to tri-state the Receiver outputs regardless of the input data stream. By pulling
TRIRXD "High", the Receiver outputs will automically tri-state.
