DESCRIPTION
STLC5432, CMOS device, interfaces the multi-
plex system to the physical CEPT Transmission
link at 2048Kb/s. Furthermore, thanks to its flexi-
bility, it is the optimum solution also for the ISDN
application as PRIMARY RATE CONTROLLER.
The receive circuit performances exceed CCITT
recommendation and the line driver outputs meet
the G.703 specifications.
STLC5432 is the real single chip solution that al-
lows the best system flexibility and easy design.
STLC5432 can work either in 2048 or 4096 or
8192 Kbit/s systems programming the CR4 regis-
ter (when parallel micro interface selected).
