Overview
The new Infineon Technologies generation of highly integrated ISDN circuits enables design engineers to decrease board size and thus PBX size and its production costs.

FEATUREs
• Eight full duplex 2B+D UPN interface transceivers, each equipped with the following functions:
    –Conversion from/to binary to/from pseudo-ternary code
    –Receive timing recovery
    –Activation/deactivation procedures, triggered by primitives received over the IOM interface or by INFO received from the line (e.g. detection of INFO 1)
    –Line Delay Measurement
    –Execution of test loops
    –Analog line transceiver for up to 16 dB line attenuation
    –UPN interface functions compatible to PEB 2095, IBC, and PEB 20950, ISAC-P (except for looplength)
    –UPN interface fully compatible to PSB 2196, ISAC-P TE, PSB 2197, SmartLink-P, SCOUT
• IOM-2 interface
• Support for JTAG boundary scan test
• 1µ CMOS technology with low power consumption
• P-MQFP-44 package
