KS8620

INTRODUCTION

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.

FEATURES

• Complete CODEC and filtering system

• Encoding / Decoding : 8 bits
