SBAS495D June 2010 – August 2021 PCM9211
PRODUCTION DATA
The PCM9211 is an analog and digital front-end device for any media player and recorder. It integrates a 216-kHz digital audio transceiver (DIX), a 96-kHz stereo ADC, and multiple PCM (I2S, left-justified, right-justified) interfaces. Additionally, the device integrates a router that allows any source (ADC, 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 PCM9211 (that is, the ADC, 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 PCM9211 also features a power down function that can be set using hardware pins and registers, ensuring that the system minimizes power consumption during standby.
