2 MSPS
The three input channels
(R, G, B) are sampled in
parallel at 2 MSPS
maximum. The sampled
data is multiplexed into a
single data stream before
the internal ADC, giving an
internal serial data rate of
maximum 6 MSPS.
MCLK max: 12 Mhz
MCLK: VSMP ratio is 6:1
Setup register 1:
Word 1: 00h
Word 2: 81h
