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.
