General Description
The Signal Processing Subscriber Line Interface Codec Filter SLICOFI (PEB 3065/PEF 3065) is a logic continuation of the well established family of the SIEMENS PCM-Codec-Filter-ICâs with the vertical integration of all DC-feeding, Supervision and Meterpulse Injection features on chip as well. Fabricated in a standard 1 µm BiCMOS technology the SLICOFI is tailored for very flexible solutions in digital communication systems.
