HI3197
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.
