10-Bit, 125 MSPS D/A Converter

The HI3197 is a high-speed D/A converter which can perform the multiplexed input of the two system 10-bit data. The maximum conversion rate achieves 125 MSPS. The multiplexed operation is possible by the 1/2 frequency divided clock or by halving the frequency of the clock with the clock frequency divider circuit having the reset pin in the IC. The data input is TTL; the clock input pin and reset input pin can select either TTL or PECL according to the application.
