Introduced to specifically meet the needs of automotive audio platforms, the CS42435 audio codec incorporates features such as a flexible power supply, level translators and digital integration. This IC simplifies the designers’ job, allowing them to deliver advanced multichannel surround-sound performance for entry- and mid-level audio products, all in a single 52-pin LQFP package. The CS42435 allows up to four single ended or differential-audio input sources and up to eight single-ended or differential output sources. This high level of integration eliminates the need for external analog-to digital (A/D) converters to pass multiple audio channels to a DSP chip for audio processing. An auxiliary serial input is available for an additional two channels of PCM (pulse code modulation) data. The increased input capability enables audio/video (A/V) receivers that receive audio from several sources. In an automotive entertainment system, the audio input sources could include in-car navigation systems, mobile phones, CD/DVD players as well as the radio tuner. The CS42435 delivers advanced performance, design flexibility, a reduction in BOM costs and competitive price-points. This product is ideal for audio applications such as A/V receivers, DVD receivers and automotive audio systems, applications that require wide dynamic range, negligible distortion and low noise.
