Description
General part information
PCMD3140-Q1 Series
The PCMD3140-Q1 is a high-performance, pulse-density-modulation (PDM) input to time-division multiplexing (TDM) or I2S output converter that supports simultaneous sampling of up to four digital channels for the PDM microphone input. The device integrates programable digital volume control, a microphone bias voltage, a phase-locked loop (PLL), a programmable high-pass filter (HPF), biquad filters, low-latency filter modes, and allows for output sample rates up to 768 kHz. The device supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with the I2C interface. Additionally, the PCMD3140-Q1 supports master and slave mode selection for the audio bus interface operation. These integrated high-performance features, along with the ability to be powered from a single-supply of 3.3 V or 1.8 V, make the device an excellent choice for space-constrained audio systems in far-field microphone recording applications.
The PCMD3140-Q1 is specified from –40°C to +125°C, and is offered in a 20-pin WQFN package.
