TP3155 Time Slot Assignment Circuit
General Description
The TP3155 is a monolithic CMOS logic circuit designed to
generate transmit and receive frame synchronization pulses
for up to 8 COMBOTM CODEC/Filters. Each frame sync
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
TP3020/TP3021 and 2910/2911 CODECs, enabling an
easy upgrade to COMBO CODEC/Filters to be made.
Features
Y Controls up to 8 COMBO CODEC/Filters
Y Independent transmit and receive time slot assignments
Y 8-channel unidirectional mode
Y Up to 32 time slots per frame
Y Serial control interface compatible with TP3020/TP3021
CODECs
Y LS TTL and CMOS compatible inputs
Y 5 mW, 5V operation
