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.
20-CERDIP
FEATURES
l Single, 5V operation
l Low power consumption: 5mW
l Controls four 1 CHIP CODEC
l Independent transmit and receive frame syncs
enables
l channel unidirectional mode
l Up to 64 time slots per frame
l Compatible with KT8554/7 CODECs
l TTL and CMOS compatible

TIME SLOT ASSIGNMENT CIRCUIT
APPLICATION CIRCUIT
The KT8555 TSAC combined with any kind of 1 CHIP CODEC from KT8554/7 series can obtain data timing as illustrated
in Fig. 3. Even though FSX output goes high before BCLK gets high, the DX output of the 1 CHIP CODEC remains in the
TRI-STATE mode until both outputs are high. The eight bit period is shortened to avoid PCM data clash at PCM pre-
highway.
Alternatively, full 8 bits can be obtained by inverting the BCLK to the 1 CHIP CODEC devices, thereby rising edges of
BCLK and FSX/R are aligned.
Fig. 4 is typical timing of the control data interface.
Fig. 5 is the typical application circuit at operating control mode 2.
