ISL58315

• Product Introduction

Key features:

High-speed, three-output laser diode driver, supported HD resolution up to 720 pixels Up to 1A peak current output Fast output switching speed and pulse rise/fall time Sharp pixels from 1ns to 2ns Intersil's patented laser voltage sampling feature provides dynamic power management capabilities, resulting in a significant reduction in system power consumption Intersil's patented SmartLinearizer™DAC provides a linear transfer function (green laser output input video code) that eliminates the need for DSP controller processing algorithms required for nonlinear green lasers Flexible 10-bit or Intersil's patented 15-bit RGB pixel input format support for reduced speed and power. The maximum data input rate of 300MHz supports 10-bit RGB mode LDD's blanking time is reduced, power consumption is reduced by 3 milliamps, and typical current consumption is lowered Programmable return to zero (RTZ) capability for maximum flexibility The integrated heater function of the doubled green laser reduces external components Single 3.3V power supply and 1.8V video interface, compatible with low power consumption description

ISL58315 is a high-speed, three-output laser diode driver (LDD) laser scanning projection system that requires three channels of independent current control at high speed.

Each output channel provides independent laser threshold and color DAC current control. The independent-scale DAC allows for independent scaling of threshold and color DAC output values. This allows for projector brightness control that can be used to simplify automatic power calibration (APC) for laser-based systems.

High-speed 10-bit or 15-bit parallel video interface for LDD transmission of pixel data information. Three parallel interface modes provide flexibility and allow the user The trade-off between speed, power and bus width. Pixel data, with a plan with double data rate, allows video data to be delivered using two clock edges.
