PEB2466HV2.2

Product Summary

The PEB2466HV2.2 is a 4-channel Signal Processing Codec Filter. It is the logical continuation of a well established family of SIEMENS programmable codec-filter-ICs. Its major difference to the PEB2465 (SICOFI-4) is the PCM and mC interface, which replaces the IOM-2 interface. The PEB2466HV2.2 is a fully integrated PCM CODEC and FILTER fabricated in low power 1m CMOS technology for applications in digital communication systems.
