Stereo Audio

DIGITAL-TO-ANALOG CONVERTER

with VCXO and PLL

FEATURES

DESCRIPTION

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 mas-

ter clock source, and support for multiple audio-sampling

frequencies.

● COMPLETE DELTA-SIGMA STEREO DAC

● VOLTAGE-CONTROLLED CRYSTAL

OSCILLATOR: 27MHz ±150ppm Output with

0V to 3V Input

● PROGRAMMABLE PLL

256f_Sor 384f_SAudio System Clock Output

The stereo D/A converter utilizes multi-bit, delta-sigma

architecture, which includes an 8x interpolation filter, third-

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.

● DYNAMIC PERFORMANCE:

Dynamic Range: 94dB

SNR: 94dB

THD+N: –89dB

● SAMPLING FREQUENCIES:

16kHz, 22.05kHz, 24kHz

32kHz, 44.1kHz, 48kHz

64kHz, 88.2kHz, 96kHz
