Description
The CXA3778 is a high-speed 10-bit D/A converter with multiplexed input. It has a maximum conversion rate of 125MSPS, and its clock and reset inputs can select either TTL or PECL level depending on the application. The data input is at TTL level, and the IC has a 2:1 multiplexed input function. It also has a built-in clock frequency divider circuit that allows for a 1/2 frequency-divided clock output. The CXA3778 has a voltage output that can drive a 50Ω load and can be operated using a single power supply or ±dual power supply.
