Winbond Electronics W83194R-630, W6630CR Datasheet
W6630CR
STEREO AUDIO DAC
GENERAL DESCRIPTION
The W6630CR 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 16 or 18 Bit linear input
data for DAC consists of two formats, normal format
and I 2S 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 4x9 bits internal control registers can be
controlled by the serial setup port (SSP). Many functions
such as 256 step attenuation, DAC mute, digital deemphasis and format conversions can be set up through
these registers.
