The overall filter response for the AD6636 is the composite of
all the combined filter stages. Each successive filter stage is
capable of narrower transition bandwidths but requires a
greater number of CLK cycles to calculate the output. More
decimation in the first filter stage minimizes overall power
consumption. Data from the device is interfaced to a
DSP/FPGA/baseband processor via either high speed parallel
ports (preferred) or a DSP-compatible microprocessor interface.
The AD6636 is available both in 4-channel and 6-channel
versions. The data sheet primarily discusses the 6-channel part.
The only difference between the 6-channel and 4-channel
devices is that Channel 4 and Channel 5 are not available on the
4-channel version, (see Figure 1). The 4-channel device still has
the same input ports, output ports, and memory map. The
memory map section for Channel 4 and Channel 5 can be
programmed and read back, but it serves no purpose.
