S5T8554B Datasheet, PDF (1/14 Pages) Samsung semiconductor – 1 CHIP CODEC

1 CHIP CODEC
INTRODUCTION
The S5T8554B/7B are single-chip PCM encoders and decoders
(PCM CODECs) and PCM line filters. These devices provide all the
functions required to interface a full-duplex voice telephone circuit
with a time-division-multiplex (TDM) system.
These devices are designed to perform the transmit encoding and
receive decoding as well as the transmit and receive filtering
functions in PCM system. They are intended to be used at the
analog termination of a PCM line or trunk.
These devices provide the bandpass filtering of the analog signals
prior to encoding and after decoding. These combination devices
perform the encoding and decoding of voice and call progress tones
as well as the signalling and supervision information.
