SLEU079 – September 2006

Description

The DEM-DAI3052A is an evaluation board for the PCM3052A, a 96-kHz, 24-bit stereo
audio coder/decoder (codec), with digital audio interface receiver/transmitter, optical
and coaxial interface, onboard clock generator, –6-dB amplifier with LPF for ADC and
4-dB amplifier with LPF for DAC, switches or jumpers for mode or clock control, and
interface connector with PC for serial mode control.

The DEM-DAI3052A operates under 5-V and

±

15-V analog power supplies, with

1-Vrms or 2-Vrms unbalanced analog signal input and 2-Vrms unbalanced analog
signal output.
