More Information

The PCM6480-Q1 is a high-performance audio converter that supports simultaneous sampling of up to a 4-channel analog microphone or a line input with up to a 4-channel digital pulse density-modulation (PDM) microphone input. The device integration enables both in-cabin active noise cancellation (ANC) and voice recognition (VR) applications in a very efficient manner by simultaneously using the analog and digital microphone input sampling. The PCM6480-Q1 consists of high-performance, audio analog-to-digital converters (ADCs) that support analog input signals up to 10 VRMS. The device offers an integrated high-voltage, programmable microphone bias, and input diagnostic circuitry that allow direct connection to microphone-based automotive systems with full fault diagnostic capability for DC-coupled inputs. The device integrates an efficient boost converter to generate a high voltage microphone bias using an external, low-voltage, 3.3-V supply, which is a readily available supply in the system. The PCM6480-Q1 integrates the programable channel gain, digital volume control, a low-jitter phase-locked loop (PLL), a programmable high-pass filter (HPF), biquad filters, low-latency filter modes, and allows for sample rates up to 768 kHz. The PCM6480-Q1 supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with either the I2C or SPI interface.
