PCM CodecâFilter MonoâCircuit
Legacy Device: Motorola MC145502, MC145503, MC145505
The ML145502, ML145503, and ML145505 are all per channel PCM
CodecâFilter monoâcircuits. These devices perform the voice digitization
and reconstruction as well as the band limiting and smoothing required
for PCM systems. The ML145503 is a general purpose device that is
offered in a 16âpin package. These are designed to operate in both syn-
chronous and asynchronous applications and contain an onâchip preci-
sion reference voltage. The ML145505 is a synchronous device offered in
a 16âpin DIP and wide body SOIC package intended for instrument use.
The ML145502 is the fullâfeatured device which presents all of the
options of the chip. This device is packaged in a 22âpin DIP and a
28âpin chip carrier package
These devices are pinâforâpin replacements for Motorolaâs first genera-
tion of MC14400/01/02/03/05 PCM monoâcircuits and are upwardly
compatible with the MC14404/06/07 codecs and other industry standard
codecs. They also maintain compatibility with Motorolaâs family of
MC33120 and MC3419 SLIC products.
The ML1455xx family of PCM CodecâFilter monoâcircuits utilizes
CMOS due to its reliable lowâpower performance and proven capability
for complex analog/digital VLSI functions.
