ML145506
PCM Codec–Filter Mono–Circuit
Legacy Device:
Motorola MC145506
The ML145506 is a per channel codec–filter PCM mono–circuit. This
device performs the voice digitization and reconstruction, as well as the
band limiting and smoothing required for PCM systems. This device has
HCMOS compatible digital outputs and supplements the Lansdale
ML145502 – ML145505 series of PCM codec–filters. The ML145506 is
functionally similar to the ML145502. It is designed to operate in both
synchronous and asynchronous applications and contain an on–chip pre-
cision reference voltage. The ML145506 is offered in a 22–pin package
and has the capability of selecting from three peak overload voltages (2.5
V 3.15 V and 3.78 V).

This device maintains compatibility with Motorola’s family of
MC3419/MC33120 SLIC products.
The ML1455xx family of PCM codec–filter mono–circuits utilize
CMOS due to its reliable low–power performance and proven capability
for complex analog/digital VLSI functions.
