SBAS057A – JANUARY 1996 – REVISED MAY 2007

Stereo Audio

DIGITAL-TO-ANALOG CONVERTER

With Programmable PLL

FEATURES

● ACCEPTS 16-, 20-, OR 24-BIT INPUT DATA

DESCRIPTION

The PCM1723 is a complete, low-cost, stereo audio

digital-to-analog converter (DAC) with a phase-locked

loop (PLL) circuit included. The PLL derives either a

256f_Sor 384f_Ssystem clock from an external 27MHz

reference frequency. The DAC contains a 3rd-order

delta-sigma (∆Σ) modulator, a digital interpolation filter,

and an analog output amplifier. The PCM1723 can

accept 16-, 20-, or 24-bit input data in either normal or

I²S formats.

● COMPLETE STEREO DAC: Includes Digital Filter

and Output Amp

● DYNAMIC RANGE: 94dB

● MULTIPLE SAMPLING FREQUENCIES:

16kHz, 22.05kHz, 24kHz

32kHz, 44.1kHz, 48kHz

64kHz, 88.2kHz, 96kHz

● PROGRAMMABLE PLL CIRCUIT:

256f_S/384f_Sfrom 27MHz Master Clock

● NORMAL OR I²S™ DATA INPUT FORMATS

The digital filter performs an 8X interpolation function

and includes selectable features such as soft mute,

digital attenuation and digital de-emphasis. The PLL

can be programmed for sampling at standard digital

audio frequencies as well as one-half and double

sampling frequencies.

● SELECTABLE FUNCTIONS:

Soft Mute

Digital Attenuator (256 Steps)

Digital De-emphasis

The PCM1723 is ideal for applications which combine

compressed audio and video data such as DVD, DVD-

ROM, set-top boxes and MPEG sound cards.

● OUTPUT MODE: Left, Right, Mono, Mute
