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.

Features

• 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

• RGB scanning laser projection system

• Programmable multi-pulse Return to Zero (RTZ) function to

provide maximum flexibility

• Laser-based projectors

• Single 3.3V supply and 1.8V video interface compatible for

low power systems

• Generic laser-based applications requiring multiple

independently controlled lasers or a single high current

driver

• 3-wire SPI interface

• Operating temperature range: -40°C to +125°C

• AEC-Q100 qualified
