描述 Description

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. The data input is at TTL level, and the clock input and reset input can select either TTL or PECL level according to the application.
