PCM MACROCELL DEMONSTRATOR

The MV1403 contains 8 PCM macrocells which can be configured so as to perform the common channel signalling and error detection functions for a 2.048 Mbit 30 channel PCM transmission link, operating to the appropriate CCITT recommendations. The MV1403 also allows access to all the macrocells individually and is implemented in GPS CMOS technology utilising the CLA60000 series gate array, offering high performance, low power and fast turn-round. The following macrocells are included in the MV1403.
