MC145507

The MC145506, MC145507, and MC145508 are per channel codecfilter PCM monocircuits. These devices perform the voice digitization and reconstruction, as well as the band limiting and smoothing required for PCM systems. These devices have HCMOS compatible digital outputs and otherwise supplement the MC145500 MC145505 series of PCM codecfilters. The MC145506, MC145507, and MC145508 are functionally similar to the MC145502, MC145503, and MC145505, respectively. MC145506, MC145507, and MC145508 are designed to operate in both synchronous and asynchronous applications and contain an onchip precision reference voltage. The MC145506 is offered in a 22pin package and has the capability of selecting from three peak overload voltages (2.5 V, 3.15 V, and 3.78 V). The MC145507 and MC145508 offer versatility and low cost in 16pin DIP and wide body SOIC packages. Most of the features of MC145506, MC145507, and MC145508 can be made available in a lower pin count package tailored to a specific user's application. Contact the factory for further details.

MC145506, MC145507, and MC145508 maintain compatibility with Motorola's family of MC3419/ MC33120 SLIC products.

The MC145506, MC145507, and MC145508 of PCM codecfilter monocircuits utilize CMOS due to its reliable lowpower performance and proven capability for complex analog/digital VLSI functions.
