INPUT CROSSBAR MATRIX
The AD6654 has one ADC input port and six channels. Each
channel can individually select its input source from either the
real ADC input port, or from an internally generated pseudo
random sequence (referred to as a PN sequence) generator.
Each channel has an input crossbar matrix to facilitate selection
of the input signal source.
The selection of input signal for a particular channel is made
using a 4-bit cross bar mux select word in the ADC input
control register.

Each channel has a separate selection for individual control.
Cross bar mux selection enables each channel to select its input
signal source.
Table 14 gives the valid combinations of cross bar mux select
values and the corresponding input signal selections.
