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.
