KS8620
INTRODUCTION
1 Chip CODEC for Digital Answering phone
The KS8620 consists of on-chip PCM encoders, decoders
(PCM CODECs) and PCM line filter. This device
provide all the functions required to interface a full-
duplex voice telephone circuit, digital answering phone.
This device is designed to perform the transmit encoding
and receive decoding as well as the transmit and receive
filtering function in PCM system. Also it is intended to be
used at the analog termination of a PCM line / trunk.
This device provide the Band pass filtering of the analog
signals prior to encoding and after decoding. This
combination device performs the encoding and decoding
of voice and call progress tones as well as the signaling
and supervision information.
