KT8555
TIME SLOT ASSIGNMENT CIRCUIT
INTRODUCTION
The KT8555 is a per channel Time Slot Assignment Circuit
(TSAC) that produces 8-bit receive and transmit time slots for
four 1 CHIP CODEC.
Each frame synchronization pulse may be independently
assigned to a time slot in a frame of up to 84 time slots.
