Overview

Preliminary W6630CR STEREO AUDIO DAC 1.
GENERAL DESCRIPTION The Winbond W6630 is a stereo audio DAC chip incorporating 8X digital interpolatioin filters, 64X multi-level oversampling delta-sigma modulators, analog low-pass filter and output amplifiers.
The operation voltage for this chip can be from 2.
7 volt to 5.
25 volt.
Moreover, the 16 or 18 Bit linear input data for DAC consists of two formats, normal format and I2S format.
In addition, the device includes two control modes.
One is hardware mode which can control mute and digital de-emphasis.
The other one is software mode, where 4 x 9 bits internal control registers can be controlled by the serial setup port (SSP).
Many functions such as 256 step attenuation, DAC mute, digital de-emphasis and format conversions can be setup through these registers.
Because the device can reach into the high performance and low-cost design , the main application for this device is used as some consumers system such as the VCD system, CD player system, and MPEG audio system .
