PEB20321HV1.2

The PEB20321HV1.2 is designed as one kind of ISDN Subscriber Access Controller that is based on the ISAC-S PEB 2086, and provides enhanced features and functionality. PEB20321HV1.2 includes the S-transceiver (Layer 1), an HDLC controller for the D-channel and one B-channel protocol controller (HDLC or transparent) with advanced CMOS technology.

Features of the PEB20321HV1.2 are:(1)Full duplex 2B + D S/T interface transceiver according to ITU-T I.430;(2)Successor of ISAC-S PEB 2086 in 3.3 V technology;(3)Serial control interface (SCI);(4)Microcontroller access to all IOM-2 timeslots;(5)Various types of protocol support (Non-auto mode, transparent mode, extended transparent mode);(6)One D-channel HDLC controller with 64 byte FIFOs per direction;(7)One B-channel HDLC controller with reduced functionality (e.g. for firmware upgrades);(8)Monitor channel handler (master/slave);(9)IOM-2 MONITOR and C/I-channel protocol to control peripheral devices;(10)Conversion of the frame structure between the S/T-interface and IOM-2.

The absolute maximum ratings of the PEB20321HV1.2 can be summarized as:(1)Ambient temperature under bias: 0 to +70 °C;(2)Storage temperature: -55 to 150 °C;(3)Input/output voltage on any pin with respect to ground: -0.3 to 5.25 V;(4)Maximum voltage on any pin with respect to ground: 5.5 V.
