description

The 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 modulation.

Each output channel provides independent laser threshold and current control of the color DAC. Independent-scale DACs allow independent scaling of thresholds and color DAC output values. This allows the projector's brightness control to be used to simplify automatic power calibration (APC) of laser-based systems.

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