General Description
The four Channel CODEC Filter PEB 2465 SICOFI-4 is the logic continuation of a
well-established family of SIEMENS codec-filter-ICs.
The SICOFI-4 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 2465 provides excellent transmission
performance and high flexibility. The new filter concept (second generation) lends to a
maximum of independence between the different filter blocks. Each filter block can be
seen like an one to one representative of the corresponding network element.
Only very few external components are needed, to complete the functionality of the
SICOFI-4. The internal level accuracy is based on a very accurate bandgap reference.
The frequency behavior 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.
