CXA3197R Overview
The CXA3197R is a high-speed D/A converter which can perform multiplexed input of two system 10-bit data. This IC realizes a maximum conversion rate of 125MSPS. Multiplexed operation is possible by inputing the 1/2 frequency-divided clock or by halving the frequency of the clock internally with the clock frequency divider circuit having the reset pin.
