The PCMD3180-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 eight digital channels for the PDM microphone input. The device integrates programmable 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 768kHz. The device supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with either the I2C or SPI interface. Additionally, the PCMD3180-Q1 supports controller and target 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 3.3V or 1.8V, make the device an excellent choice for space-constrained audio systems in far-field microphone recording applications.
The PCMD3180-Q1 is specified from –40°C to 125°C and is offered in a 24-pin WQFN package.
