Functional Description
This section describes the function of each entity on the TUPP 2488 block diagram.
CML Serial Interface Subsystems
This section describes the CML subsystems. There are two CML subsystems, one for the line
side supporting four working and four protect links and one for the system side supporting eight
working and eight protect links.
CML Interface Overview
RASIO™ CML voltage levels are used on the serial links of TUPP 2488. RASIO™ CML is
compatible with LVDS.
Figure 12 illustrates how RASIO™ CML interface functionality is achieved in TUPP 2488. The
digital blocks adapt between the internal parallel 77.76 MHz TelecomBus in TUPP 2488 and a
high speed Rate Agnostic 1.2 V RASIO™ CML Serializer/Deserializer (RA013_SERDES).
Figure 12 shows the generic structure of the subsystem building blocks for the system and line
side CML interfaces and their interface to the SERDES.
