... CDB4361 SYSTEM OVERVIEW The CDB4361 evaluation board is an excellent means of quickly evaluating the CS4361. The CS8416 digital audio interface receiver provides 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 through a PCB head- er for system development ...

... ANALOG OUTPUT FILTERING The analog output on the CDB4361 has been designed according to the CS4361 datasheet. This output circuit in- cludes an AC coupling cap and a single pole R and C. An additional load resistance may be added by shunting J23, J24, J38, J39, J42, and J43 to test the CS4361’s load-driving capability. See 7 ...

... The plots in the following section were acheived using an Audio Precision System 2700 and a randomly chosen pro- duction CDB4361. In some cases the performance may be limited by the CDB4361. All measurements were taken at room temp using the standard AP filter options ( kHz) with default board settings and nominal datasheet voltages applied unless otherwise noted ...
