DESCRIPTION

STLC5432, CMOS device, interfaces the multiplex system to the physical CEPT Transmission link at 2048Kb/s. Furthermore, thanks to its flexibility, 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 allows the best system flexibility and easy design. STLC5432 can work either in 2048 or 4096 or 8192 Kbit/s systems programming the CR4 register (when parallel micro interface selected).
