TP3155 Time Slot Assignment Circuit

General Description

The TP3155 is a monolithic CMOS logic circuit designed to

generate transmit and receive frame synchronization pulses

pulse may be independently assigned to a time slot in a

frame of up to 32 time slots Assignments are controlled by

loading in an 8-bit word via a simple serial interface port

This control interface is compatible with that used on the

TP3020TP3021 and 29102911 CODECs enabling an

easy upgrade to COMBO CODECFilters to be made
