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.
