2.3 Digital Hardware

2.3.1 Digital Filter

The CS5376A quad digital filter performs filtering and decimation of four delta-sigma bit streams from the

CS5372 modulators. It also creates a delta-sigma bit stream output to create analog test signals in the

CS4373A test DAC.

The CS5376A requires several control signal inputs from the external system.
