GENERAL DESCRIPTION
ST5451 HDLC and GCI controller is a CMOS circuit fully developed by STMicroelectronics and diffused in advanced 1.2 µm HCMOS3 technology. The device is intended to be used mainly in ISDN applications, in Terminal (TE) and in Line Terminations (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 going from GCI (General Circuit Interface) to DSI (Digital System Interface) to any PCM-like stream. ST5451 can be easily controlled by many different kind of microprocessors or microcontrollers having either non-multiplexed or multiplexed bus structure. ST5451 can be used in connection with ST5420/1 S Interface Devices (SID-µW and SID-GCI) and ST5080 Programmable ISDN Combo (PIC) in Terminals and with ST5410 U Interface Device (UID) in Line Terminations.
