General Description

The four channel Signal Processing Codec Filter PEB 2466 SICOFI-4-μC is the logical continuation of a well established family of SIEMENS programmable codec-filter-ICs.

Its major difference to the PEB 2465 (SICOFI-4) is the PCM and μC interface, which replaces the IOM-2 interface.
