DATA SHORT To request the full datasheet, please visit www.intersil.com/products/ISL58315 ISL58315 FN7543 Rev 0.00 High Speed Triple Laser Diode Drivers September 30, 2011 The ISL58315 is a high-speed, triple-output laser diode driver Features (LDD) for laser scanning projector systems, which require three channels modulated at high speed with independent current High-speed, triple-output laser diode driver supporting up to control. 720-pixel HD resolution Each output channel provides laser-independent current Up to 1A of peak current output control for threshold and color DACs. Separate scale DACs Fast output switching speeds with pulse rise/fall times of allow independent scaling of both threshold and color DAC 1ns to 2ns for crisp pixels output values. This allows control of projector brightness and Intersil patented laser voltage sampler function provides can be used to simplify automatic power calibration (APC) for laser-based systems. dynamic power management capability to dramatically minimize system power Pixel data information is transferred through the LDD s high-speed 10-bit or 15-bit parallel video interface. Three Intersil patented SmartLinearizer DAC feature provides a parallel interface modes provide flexibility and allow users a linear transfer function (input video code to green laser trade-off among speed, power and bus width. Pixel data output), eliminating the need for DSP controller processing employs a double data rate scheme, allowing video data to be algorithms required for non-linear green lasers transferred using both clock edges. Flexible 10-bit or Intersil patented 15-bit RGB pixel input formats supported to reduce speed and power. 300MHz Applications maximum data Input rate supported for 10-bit RGB mode Laser-based Pico Projectors Blanking time power reduction reduces LDD current RGB Scanning and Field-based laser projection systems consumption to 3mA typical Generic laser-based applications requiring multiple, Programmable return-to-zero (RTZ) function provides independently controlled lasers maximum flexibility Integrated heater function for SHG green lasers reduces Related Literature external components See application block diagram for Pico Projector (MEMS) at: Single 3.3V supply and 1.8V video interface compatible for ISL58315 Copyright Intersil Americas LLC 2011.
