1.3.1 ASI-to-RS-422 Support
The CMR-5940 provides state-of-the-art ASI-to-RS-422 conditioning and filtering based
on the ISO/IEC 13818-1 and DVB MPE Specification for Data Broadcasting (EN 301
192).
The CMR-5940 provides the following configuration features:
•
ASI Input:
o Automatic 188/204-byte mode format detection
o Input rates up to 213 Mbps supported
•
RS-422 Output:
o Configurable 188/204-byte mode egress format
o External Clocking – clock is provided by the attached
equipment
o Internal Clocking with output rates up to 8.192 Mbps
supported – clock is provided by the CMR-5940
1.4 Configuration
The CMR-5940 receives an MPEG-2 Asynchronous Serial Interface (ASI) input and
outputs an MPEG-2 RS-422 stream that has been filtered, Program Clock Reference
(PCR) restamped, and the egress rate is adjusted to the user’s desired configured rate.
A typical CMR-5940 application is shown in Figure 1-2.
