... CDB4340A/41A SYSTEM OVERVIEW The CDB4340A/41A evaluation board is an excel- lent means of quickly CS4340A/41A. The CS8414 digital audio interface receiver provides an easy interface to digital audio signal sources including the majority of digital au- dio test equipment. The evaluation board also al- lows the user to supply clocks and data through a 10-pin header for system development ...

... The CS4340A/41A requires careful attention to power supply and grounding arrangements to opti- mize performance. Figure 10 details the power dis- tribution used on this board. The CDB4340A/41A ground plane is split to control the digital return currents in order to minimize digital interference. The decoupling capacitors are located as close to the CS4340A/41A as possible ...
