Hardware Reference Manual
Figure 4
Figure 4 shows the functional blocks and the interface pins of the SICOFI
• Two 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;
• An IOM-2 PCM interface with time slot assignment, one input and one output
• Three clock inputs, DCL, BCL, and FSC also apply to the IOM-2 PCM Interface;
• 14 signaling input and output pins, accessible through registers;
• Two interrupt outputs, one for each channel-pair 1&2, and 3&4;
• One interrupt output;
• On-chip PLL for an internal 16,384 kHz clock;
• Eight common configuration registers (XR-Registers) affecting both channels;
• Two sets of six channel-specific registers (CR-Registers);
• Coefficient RAM (CRAM) for filter coefficients storage for each channel;
• The Serial Microcontroller Interface has four signals: DIN, DOUT, DCLK, and CS#.
