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 PEB 2465 is a fully integrated PCM CODEC and FILTER fabricated in low power 1m 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 PEB 2465 can be seen like an one to one representative of the corresponding network element.

Only very few external components of PEB 2465 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 PEB 2465 works with only one single 5 V supply there is a very good dynamic range available.
