Rev 2.00
October 20, 2016 Automotive High-Speed Quad Laser Diode Driver Features The ISL78365 high-speed, quadruple output Laser Diode
Driver (LDD) is designed to support high speed RGB/RGGB
laser scanning projection systems. High-speed quadruple output laser diode driver supporting
up to 150MHz maximum output pixel clock 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. Up to 750mA of peak current output per channel Fast output switching speeds with pulse rise/fall times of
1.5ns for crisp pixels Intersil laser voltage sampler function with integrated
dynamic power optimization controller to dramatically
minimize system power Flexible data order supports different RGB LD
opto-mechanical placement Blanking time power reduction to reduce LDD current
consumption Applications Programmable multi-pulse Return to Zero (RTZ) function to
provide maximum flexibility RGB scanning laser projection system Laser-based projectors Single 3.3V supply and 1.8V video interface compatible for …
