GENERAL DESCRIPTION
ST5451 HDLC and GCI controller is a CMOS cir-
cuit fully developed by SGS-THOMSON and dif-
fused in advanced 1.2
μ
m HCMOS3 technology.
The device is intended to be used mainly in ISDN
applications, in Terminal (TE) and in Line Termi-
nations(LT).
ST5451 can handle HDLC packets either on
16Kbit/s D channel or 64 Kbit/s B channel; it can
work with a wide range of PCM signals go-
ing
from GCI (General Circuit Interface) to DSI
(Digital
System
Interface)
stream.
ST5451 is a complete GCI controller designed to
comply with the GCI and GCI-SCIT (Special Cir-
cuit Interface for Terminal) completely handling
Monitor (M) and Command/Indicate (C/I) chan-
nels.
ST5451 can be easily controlled by many differ-
ent kind of microprocessors or microcontrollers
having either non-multiplexed or multiplexed bus
structure.
ST5451 can be used in connectionwith ST5420/1
S Interface Devices (SID-
μ
W and SID-GCI) and
ST5080 Programmable ISDN Combo (PIC) in
Terminals and with ST5410 U Interface Device
(UID) in LineTerminations.
