108 dB, 192 kHz 6-in, 6-out/8-out Multi-channel TDM Codecs
The CS42436/38 family of highly integrated audio codecs is engineered to simplify design for home theaters and automotive audio systems. These codecs allow system designers to deliver advanced multi-channel surround-sound performance for entry- and mid-level audio products. The CS42436/38 family allows up to eight single-ended or six differential audio input sources to be incorporated 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 CS42436/38 family delivers advanced performance, design flexibility, a reduction in BOM costs and competitive price-points. This family 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.
