2.8
The 8-bit Single-Ended LVTTL running at 77.76 Mbps (STS-12/STM-4) or 19.44 Mbps (STS-3/STM-1) parallel
data output 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 9.
Receive Parallel Output Interface
2.9
The parallel receiver outputs are automatically pulled "Low" or forced to a logic state of "0" during a LOS
condition to prevent data chattering unless LOS detection is disabled by asserting DLOSDIS and keeping
LOSEXT input pin "high." In addition, the user can also assert LOSEXT input pin "low" from the optical module
to force an LOS and mute the parallel receiver outputs as well (while DLOSDIS input is also low, see Figure 7.)
