DESCRIPTIONThe 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 applica-
tions requiring high-quality audio playback, a precision
tuned 27MHz master clock source, and support for mul-
tiple audio-sampling frequencies.
The stereo digital-to-analog converter (DAC) uses multi-
bit, delta-sigma architecture, which includes an 8x inter-
polation 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 I2 C-Bus interface.
