ISL78365
Automotive High-Speed Quad Laser Diode Driver
The
ISL78365
high-speed, quadruple output Laser Diode
Driver (LDD) is designed to support high speed RGB/RGGB
laser scanning projection systems.
Each output driver channel consists of independent threshold
and color DACs for greater laser control and flexibility.
Separate scale DACs allow independent scaling of both
threshold and color DAC output values to control the projector
brightness or provide simple Automatic Power Calibration
(APC) for laser based systems. Pixel data information is
transferred through the LDD's high speed 10-bit parallel video
interface. There are two parallel interface modes to allow
three or four color pixel data to be entered efficiently. Pixel
data employs a double data rate scheme, allowing video data
to be transferred using both edges of the clock.
