PEB 2466

General Description
The four channel Signal Processing Codec Filter PEB 2466 SICOFI-4- C 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 C interface, which
replaces the IOM-2 interface.
The SICOFI-4- C is a fully integrated PCM CODEC and FILTER fabricated in low power
1 CMOS technology for applications in digital communication systems. Based on an
advanced digital filter concept, the PEB 2466-H provides excellent transmission
performance and high flexibility. The new filter concept (second generation) leads to a
maximum of independence between the different filter blocks. Each filter block can be
seen like a one to one representative of the corresponding network element.
To complete the functionality of the PEB 2466 only two external capacitors per channel
are needed. The internal level accuracy is based on a very accurate bandgap reference.
The frequency behaviour is mainly determined by digital filters, which do not have any
fluctuations. As a result of the new ADC - and DAC - concepts linearity is only limited by
second order parasitic effects. Although the device works with only one single 5 V supply
there is a very good dynamic range available.
