description
The TL5632C is a low-power ultra-high-speed
video digital-to-analog converter that uses the
Advanced Low-Power Schottky (ALS) process.
The device has a three channel I/O; the red, the
blue, and the green channel. The red, blue, and
green signals are referred to collectively as the
RGB signal. An internally generated reference is
also provided for the standard video output
voltage range. Conversion of digital signals to
analog signals can be at a sampling rate of dc to
60 MHz. The high conversion rate makes the
TL5632C suitable for digital television, computer
digital video processing, and high-speed data
conversion.
