PCM1740

SBAS128B – JANUARY 2000 – REVISED MAY 2007

Stereo Audio

DIGITAL-TO-ANALOG CONVERTER

with VCXO and PLL

APPLICATIONS

● SET-TOP BOXES

FEATURES

● COMPLETE DELTA-SIGMA STEREO DAC

● DIGITAL BROADCAST RECEIVERS

● VOLTAGE-CONTROLLED CRYSTAL OSCILLATOR:

27MHz ±150ppm Output with 0V to 3V Input

● PROGRAMMABLE PLL

DESCRIPTION

256f_Sor 384f_SAudio System Clock Output

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 applica-

tions requiring high-quality audio playback, a precision

tuned 27MHz master clock source, and support for mul-

tiple audio-sampling frequencies.

● DYNAMIC PERFORMANCE:

Dynamic Range: 94dB

SNR: 94dB

THD+N: –89dB

● SAMPLING FREQUENCIES:

16kHz, 22.05kHz, 24kHz

32kHz, 44.1kHz, 48kHz

64kHz, 88.2kHz, 96kHz

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 I²C-Bus interface.

● SERIAL AUDIO INTERFACE:

Standard or I²S™ Data Formats

16-, 20-, or 24-Bit Data

● I²C-BUS™ INTERFACE FOR CONTROL

REGISTERS:

DAC

Slave Receiver Operation

7-Bit Addressing

Standard Transfer Rate (up to 100kbps)

● PROGRAMMABLE CONTROLS:
