Advance Information
PCM Codec-Filter Mono-Circuit
The MC145506, MC145507, and MC145508 are per channel codec鈥揻ilter
PCM mono鈥揷ircuits. 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 鈥?MC145505 series of PCM codec鈥揻ilters. 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鈥揷hip precision reference voltage. The MC145506 is offered in a 22鈥損in
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鈥損in 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鈥檚 application. Contact the factory for further details.
These devices maintain compatibility with Motorola鈥檚 family of MC3419/
MC33120 SLIC products.
The MC145500 family of PCM codec鈥揻ilter mono鈥揷ircuits utilize CMOS due
to its reliable low鈥損ower performance and proven capability for complex
analog/digital VLSI functions.
