PRODUCT OVERVIEW
The AD1958 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 AD1958 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 µs/15 µs
digital de-emphasis for “redbook” compact discs, as well as
de-emphasis at 32 kHz and 48 kHz sample rates.
The AD1958 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
AD1958 can be configured in left-justified, I
or DSP serial-port-compatible modes. It can support 16, 20,
and 24 bits in all modes. The AD1958 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°C.
