产品描述

The PCM3060 is a low-cost, high-performance, single-chip, 24-bit stereo audio codec with single-ended analog inputs and differential analog outputs.

The stereo 24-bit ADC employs a 64-times delta-sigma modulator. It supports 16-96 kHz sampling rates and a 16/24-bit digital audio output word on the audio interface.

The stereo 24-bit DAC employs a 64- or 128-times delta-sigma modulator. It supports 16-192 kHz sampling rates and a 16/24-bit digital audio input word on the audio interface.

The PCM3060 supports fully independent operation of the sampling rate and audio interface for the ADC and DAC.

Each audio interface supports I2S, left-justified, and right-justified formats with 16/24-bit words.

The PCM3060 can be software-controlled through a 3-wire SPI-compatible or 2-wire I2C-compatible serial interface, which provides access to all functions including digital attenuation, soft mute, de-emphasis etc.

The PCM3060 can be also used in hardware mode, which provides three basic functions.

The PCM3060 is fabricated using a highly advanced CMOS process and is available in a small 28-pin TSSOP package.

The PCM3060 is suitable for various sound processing applications for DVD-RW, digital TV, STB, and other AV equipment.
