ISL58315CRTZ-T13

Laser Drivers Overview

The ISL58315CRTZ-T13 is a high-speed, triple-output laser diode driver (LDD) designed for laser scanning projector systems. It supports up to 720-pixel HD resolution with independent current control for threshold and color DACs. The device features a maximum data input rate of 300MHz in 10-bit RGB mode and accepts flexible 10-bit or 15-bit parallel video interfaces. It operates on a single 3.3V supply with a 1.8V video interface compatibility, consuming typical current of 3mA in blanking time power reduction mode.

Laser Drivers Feature Summary

• Patented SmartLinearizer™ DAC feature provides linear transfer function eliminating DSP processing requirements
• Integrated heater function for SHG green lasers reduces external component count
• Programmable return-to-zero (RTZ) function offers maximum flexibility
• Dynamic power management via patented laser voltage sampler minimizes system power

Laser Drivers Applications

• Laser scanning projector systems requiring three channels modulated at high speed
• Automatic power calibration (APC) for laser-based projection systems
• High-speed pixel data transfer applications supporting double data rate schemes

Laser Drivers Procurement Notes

Verify the specific suffix T13 indicates reel packaging with a minimum order quantity of 6000 units when sourcing from distributors. Confirm that the part number corresponds to the Renesas/Intersil series and matches the 40-TQFN package specification. Ensure compatibility with the required 3.3V supply and 1.8V video interface levels before integration into the design.

Laser Drivers Selection Notes

Select this component for applications demanding high-speed modulation with independent channel control. The integrated SmartLinearizer™ simplifies design by removing the need for external DSP controllers for non-linear green lasers. Consider the 300MHz data rate limit and the specific 10-bit or 15-bit parallel interface modes when defining system bandwidth and bus width requirements.
