Figure 4 shows the functional blocks and the interface pins of the SICOFI
• Four independent bi-directional voice channels;
• Oversampling sigma-delta A/D and D/A converters with excellent resolution, dynamic
• Hardware filters for decimation and interpolation of the ADC and DAC bit stream, and
• DSP core with programmable, channel-independent filter structures for impedance
• Configurable A-Law or µ-Law compressor and expander units;
• Two PCM ports with data rates from 128 kbps to 8 Mbps per highway;
• Programmable time slot assignment for each channel;
• twenty-eight signaling input and output pins, accessible through registers;
• On-chip PLL for an internal 16.384 MHz clock;
• Two programmable versatile clock outputs;
• Eight common configuration registers (XR-Registers) affecting all four channels;
• Four sets of six channel-specific registers (CR-Registers); and
• Coefficient RAM (CRAM) for filter coefficients storage for each channel.
