Designing with the LIU
In this section, we will discuss the following topics.
How to design with and configure the LIU to permit a system to meet the above-mentioned Intrinsic Jitter and
Wander requirements.
How is the LIU able to meet the above-mentioned requirements?
How does the LIU permits the user to comply with the SONET APS Recovery Time requirements of 50ms
(per Telcordia GR-253-CORE)?
How should one configure the LIU, if one needs to support "Daisy-Chain" Testing at the end Customer's site?
7.8.1
How to design and configure the LIU to permit a system to meet the above-mentioned
Intrinsic Jitter and Wander requirements
As mentioned earlier, in most application (in which the LIU will be used in a SONET De-Sync Application) the
user will typically interface the LIU to a Mapper device in the manner as presented below in Figure 65.
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 65 presents a simple illustration as to how one channel, within the LIU should be connected to the
Mapper IC.
As mentioned above, the Mapper IC will typically output a Clock and Data signal to the LIU. In many cases,
the Mapper IC will output the contents of an entire STS-1 data-stream via the Data Signal to the LIU. However,
the Mapper IC typically only supplies a clock pulse via the Clock Signal to the LIU 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.
Figure 65 indicates that the Data Signal from the Mapper device should be connected to the TPDATA_n input
pin of the LIU IC and that the Clock Signal from the Mapper device should be connected to the TCLK_n input
pin of the LIU IC.
In this application, the LIU has the following responsibilities.
