Triple 8-Bit, 40MSPS, RGB, 3-Channel D/A
Converter
The HI1178 is a triple 8-bit, high-speed, CMOS D/A
converter designed for video band use. It has three
separate, 8-bit, pixel inputs, one each for red, green, and
blue video data. A single 5.0V power supply and pixel clock
input is all that is required to make the device operational. A
bias voltage generator is internal. Each channel clock input
can be controlled individually, or connected together as one.
The HI1178 also has BLANK video control signal.
