PCM Codec-Filter Mono-Circuit
The MC145506, MC145507, and MC145508 are per channel codec–filter
PCM mono–circuits. 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 codec–filters. The
MC145506, MC145507, and MC145508 are functionally similar to the
MC145502, MC145503, and MC145505, respectively. They are designed to
operate in both synchronous and asynchronous applications and contain an
on–chip precision reference voltage. The MC145506 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). The MC145507 and MC145508 offer versatility and
low cost in 16–pin DIP and wide body SOIC packages. Most of the features of
these devices 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 maintain compatibility with Motorola’s family of MC3419/
MC33120 SLIC products.
The MC145500 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.
