MC145503 General Description


The MC145500, MC145501, MC145502, MC145503, and MC145505 are all per channel PCM CodecFilter monocircuits. 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 16pin package. They are designed to operate in both synchronous and asynchronous applications and contain an onchip precision reference voltage. The MC145501 is offered in an 18pin 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 16pin DIP and wide body SOIC package intended for instrument use. The MC145502 is the fullfeatured device which presents all of the options of the chip. This device is packaged in a 22pin DIP and a 28pin 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 pinforpin replacements for Motorola's first generation of MC14400/01/02/03/05 PCM monocircuits 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 CodecFilter monocircuits utilizes CMOS due to its reliable lowpower performance and proven capability for complex analog/digital VLSI functions.
