CM6120-S
Best USB Audio Single Chip for PC Speakers Solution
DESCRIPTION
CM6120S series is a highly integrated single chip for
USB speaker application with 2-Channel Class-D
output. Minimum external components are needed
for building an USB speaker system, which makes
CM6120S a simple and very cost-effective solution.
Since no driver is necessary for audio playback on
all major OS. CM6120S provides a truly
plug-and-play feature for external digital audio
playback.
For energy saving, USB suspend mode and resume
is supported by CM6120S. This new single chip not
only support 44.1KHz and 48KHz sampling rate
playback but also with X2 modulation for
hi-frequency quality. Better yet, simplify anti-pop
noise solution was embedded on chip for general
pop noise issues. All of the functions have been
approved by USB IF certification program.
