Overview
1 Overview
The two-channel codec filter PEB 2266 SICOFI®2-µC is built around a central DSP-core
which provides independent filter structures for all channels. Its analog I/O pins are used
to connect to external subscriber line interface circuits (SLICs). Their signals are
internally routed to the analog-to-digital and digital-to-analog converters (ADC, DAC).
The signaling pins carry line status and control information to and from the SLICs. Two
programmable clock outputs are available. The SICOFI®2-µC connects to the digital
switching and transmission system through two PCM Highways. The digitized voice
band signals are available as A-Law or µ-Law codes within selectable 8-bit time slots.
The SICOFI®2-µC modes, features, and filter characteristics are programmed through a
serial interface to a microcontroller. The access mechanism is very simple, and can be
implemented with as few as three I/O ports. The PEB 2266 is available for standard
temperature range applications (0 °C to +70 °C); the PEF 2266 is available for extended
temperature range applications (-40 °C to +85 °C).
