产品概述
The PCM1740 is a complete stereo audio digital-to-analog converter with on-chip PLL and VCXO. The PCM1740 is designed specifically for set-top box applications requiring high-quality audio playback, a precision tuned 27MHz master clock source, and support for multiple audio-sampling frequencies.The stereo digital-to-analog converter (DAC) uses multibit, delta-sigma architecture, which includes an 8x interpolation filter, 3rd-order noise shaping, 5-level amplitude quantization, and an analog low-pass filter. The PCM1740 includes a number of user-programmable functions, which are accessed via a standard I2C-Bus interface.
