PRODUCT OVERVIEW

The AD1959 is a complete high-performance single-chip stereo

digital audio playback system. It is comprised of a multibit sigma-

delta modulator, digital interpolation filters, and analog output

drive circuitry with an on-board dual PLL clock generator.

Other features include an on-chip stereo attenuator and mute,

programmed through an SPI-compatible serial control port.

The AD1959 is fully compatible with all known DVD formats

including 96 kHz and 192 kHz sample frequencies and 24 bits.

It also is backwards-compatible by supporting 50

s/15

digital de-emphasis for “redbook” compact discs, as well as

de-emphasis at 32 kHz and 48 kHz sample rates.

The AD1959 has a simple but flexible serial data input port that

allows for glueless interconnection to a variety of ADCs, DSP

chips, AES/EBU receivers, and sample rate converters. The

AD1959 can be configured in left-justified, I

S, right-justified,

or DSP serial-port-compatible modes. It can support 16, 20,

and 24 bits in all modes. The AD1959 accepts serial audio data

in MSB first, two’s-complement format, and operates from a

single 5 V power supply. It is fabricated on a single monolithic

integrated circuit and housed in a 28-lead SSOP package for

operation over the temperature range –40

C to +105
