Introduction

The DIX9211 is a complete analog and digital front-end for today's multimedia players and recorders. The DIX9211 integrates an S/PDIF transceiver with up to 12 multiplexed inputs and 3x PCM inputs to allow other audio receivers to be multiplexed along with the analog and S/PDIF signals to a digital signal processor (DSP). The DIX9211 is an analog and digital front-end device for any media player/recorder. It integrates a 216-kHz Digital Audio Transceiver (DIX) and multiple PCM (I2S, Left-Justified, Right-Justified) interfaces. Additionally, the device integrates a router that allows any source (DIR or PCM) to be routed to one of three outputs (2x PCM and DIT), thus significantly reducing the number of external components required to route sources to the core DSP. Each audio interface of the DIX9211 (that is, the DIT and DIR) can operate asynchronously at different sampling rates, allowing an analog source to be sampled at 96 kHz and to be switched over to an S/PDIF source driving encoded data at 48 kHz. The DIX9211 also features a power down function that can be set via hardware pins and registers, ensuring that the system minimizes power consumption.
