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).
