... Inputs for DSD Clocks and Data http://www.cirrus.com Description The CDB4364 evaluation board is an excellent means for quickly evaluating the CS4364 24-bit, 48-pin, 6- channel, single-ended D/A converter. Evaluation re- quires an analog signal analyzer, a digital signal source for controlling the CS4364 (only required for con- trol port mode), and a power supply ...

... The evaluation board also allows the user to supply external PCM or DSD clocks and data through PCB headers for system development. The CDB4364 uses the CDB4385 as a base PCB board. For this reason, there may be additional circuitry on board which is not populated as it has no function for this device. ...

... CS4364 as possible. Extensive use of ground plane fill in the evaluation board yields large reductions in radiated noise. 7. ANALOG OUTPUT FILTERING The analog output on the CDB4364 has been designed according to the CS4364 datasheet. This output circuit in- cludes a passive 1-pole, 150 kHz filter with an AC coupled output. CONNECTOR ...
