DESCRIPTION

The SA8702 (BMTSAC) is a Block Mode

Time Slot Allocation Circuit. The device is

used to generate 8 consecutive timeslots

in one of 4 blocks in a 32 time-slot PCM

system. Each timeslot pulse is 8 BLCK

cycles long. BCLK is the 2,048 station

clock provided by the system. An active

MRST will disable all outputs until a valid

XSYNC input is recognised. The output

TSX is delayed by half a cycle and indicates

that one of 8 timeslots is currently active.

There are 4 possible modes of operation,

selectable by means of the BL0 and BL1

pins (See Table 1).

PIN CONNECTIONS

All inputs and outputs are C-MOS

compatible. All outputs are push-pull with

the exception of TSX which is open drain.

The inputs MRST and BCLK are Schmitt

Trigger. Inputs BL0 and BL1 have pull-ups.
