... THE CDB4354 SYSTEM The CDB4354 is a dedicated platform for evaluating the CS4354. The CS8416 digital audio interface receiver pro- vides an easy interface to digital audio signal sources, including the majority of digital audio test equipment. The evaluation board also allows the user to supply external PCM clocks and data directly to the CS4354 through a head- er block for system development ...

... Analog Output Filtering The analog output filter circuitry on the CDB4354 has been designed according to the CS4354 datasheet. This circuit is a first order resistor-capacitor low pass filter with values 470 /2.2 nF, respectively, which sets the -3 dB pole at 154 kHz. The resulting filter keeps signal attenuation below 0 kHz while provid- ing sufficient filtering for noise outside the audio band ...
