CXD2303AQ
8-bit 3-channel 50 MSPS Video A/D Converter with clamp function
Description
The CXD2303AQ is an 8-bit 3-channel CMOS A/D
converter for video with synchronizing digital clamp
function. The adoption of 2 step-parallel method
achieves low power consumption and a maximum
conversion rates of 50 MSPS.
