DESCRIPTION

The ETC5057/ETC5054 family consists of A-law

and

µ–law

monolithic PCM CODEC/filters utilizing

the A/D and D/A conversion architecture shown in

the block diagram below, and a serial PCM inter-

face. The devices are fabricated using double-

poly CMOS process. The encode portion of each

device consists of an input gain adjust amplifier,

an active RC pre-filter which eliminates very high

frequency noise prior to entering a switched-ca-

pacitor band-pass filter that rejects signals below

200 Hz and above 3400 Hz. Also included are

auto-zero circuitry and a companding coder which

samples the filtered signal and encodes it in the

companded A-law or

µ–law

PCM format. The de-

code portion of each device consists of an ex-

panding decoder, which reconstructs the analog

signal from the companded A-law or

µ–law

code,

a low-pass filter which corrects for the sin x/x re-

sponse of the decoder output and rejects signals

above 3400 Hz and is followed by a single-ended

power amplifier capable of driving low impedance

loads. The devices require 1.536 MHz, 1.544

MHz, or 2.048 MHz transmit and receive master

clocks, which may be asynchronous, transmit and

receive bit clocks which may vary from 64 kHz to

2.048 MHz, and transmit and receive frame sync

pulses. The timing of the frame sync pulses and

PCM data is compatible with both industry stand-

ard formats.
