The MC145500, MC145501, MC145502, MC145503, and MC145505 are all
per channel PCM Codec–Filter mono–circuits. These devices perform the voice
digitization and reconstruction as well as the band limiting and smoothing
required for PCM systems. The MC145500 and MC145503 are general
purpose devices that are offered in a 16–pin package. They are designed to
operate in both synchronous and asynchronous applications and contain an
on–chip precision reference voltage. The MC145501 is offered in an 18–pin
package and adds the capability of selecting from three peak overload voltages
(2.5, 3.15, and 3.78 V). The MC145505 is a synchronous device offered in a
16–pin DIP and wide body SOIC package intended for instrument use. The
MC145502 is the full–featured device which presents all of the options of the
chip. This device is packaged in a 22–pin DIP and a 28–pin chip carrier package
and contains all the features of the MC145500 and MC145501 plus several
more. Most of these features can be made available in a lower pin count
package tailored to a specific user’s application. Contact the factory for further
details.
These devices are pin–for–pin replacements for Motorola’s first generation of
MC14400/01/02/03/05 PCM mono–circuits and are upwardly compatible with
the MC14404/06/07 codecs and other industry standard codecs. They also
maintain compatibility with Motorola’s family of MC33120 and MC3419 SLIC
products.
The MC145500 family of PCM Codec–Filter mono–circuits utilizes CMOS
due to its reliable low–power performance and proven capability for complex
analog/digital VLSI functions.
