Designing with the XRT75L03D
In this section, we will discuss the following topics.
How to design with and configure the XRT75L03D to permit a system to meet the above-mentioned Intrinsic
Jitter and Wander requirements.
How is the XRT75L03D able to meet the above-mentioned requirements
How does the XRT75L03D permits the user to comply with the SONET APS Recovery Time requirements of
50ms (per Telcordia GR-253-CORE)
How should one configure the XRT75L03D, if one needs to support "Daisy-Chain" Testing at the end

9.8.1
How to design and configure the XRT75L03D to permit a system to meet the above-
mentioned Intrinsic Jitter and Wander requirements
As mentioned earlier, in most application (in which the XRT75L03D will be used in a SONET De-Sync
Application) the user will typically interface the XRT75L03D to a Mapper device in the manner as presented
below in Figure 57.
In this application, the Mapper has the responsibility of receiving a SONET STS-N/OC-N signal and extracting
as many as N DS3 signals from this signal. As a given channel within the Mapper IC extracts out a given DS3
signal (from SONET) it will typically be applying a Clock and Data signal to the "Transmit Input" of the LIU IC.
Figure 57 presents a simple illustration as to how one channel, within the XRT75L03D should be connected to
the Mapper IC.
Wander Measurement Test Results
As mentioned above, the Mapper IC will typically output a Clock and Data signal to the XRT75L03D. In many
cases, the Mapper IC will output the contents of an entire STS-1 data-stream via the Data Signal to the
XRT75L03D. However, the Mapper IC typically only supplies a clock pulse via the Clock Signal to the
XRT75L03D coincident to whenever a DS3 bit is being output via the Data Signal. In this case, the Mapper IC
would not supply a clock edge coincident to when a TOH, POH or any non-DS3 data-bit is being output via the
Data-Signal.
