Receive Parallel Interface LVDS Operation
When operating the 4-bit Differential bus in LVDS mode, a 402
external resistor is needed across XRES1P
and XRES1N to properly bias the RXDO[3:0]P/N and RXPCLKOP/N pins. Figure 7 shows the proper biasing
resistor installed.
2.7
Parallel Receive Data Output Mute Upon LOSD
The parallel receiver data outputs can be automatically forced "Low" during an LOSD condition to prevent data
chattering. However, the user must select the proper SDEXT polarity for the optical module used. By asserting
LOSDMUTE "High", the parallel receiver data outputs will be forced "Low" any time an LOSD condition occurs.
2.8
Parallel Receive Data Output Disable
Unlike LOSDMUTE, DISRD is used to asynchronously force the parallel receiver data outputs to zero,
regardless of the data input stream.
By asserting DISRD "High", the parallel receiver data outputs will
immediately mute.
2.9
Receive Parallel Data Output Timing
The receive parallel data output from the STS-48/STM-16 receiver will adhere to the setup and hold times
shown in Figure 8 and Table 5.
