ISL58315
The ISL58315 is a high-speed, triple-output laser diode driver
(LDD) for laser scanning projector systems, which require three
channels modulated at high speed with independent current
control. Features Each output channel provides laser-independent current
control for threshold and color DACs. Separate scale DACs
allow independent scaling of both threshold and color DAC
output values. This allows control of projector brightness and
can be used to simplify automatic power calibration (APC) for
laser-based systems. Up to 1A of peak current output Pixel data information is transferred through the LDD's
high-speed 10-bit or 15-bit parallel video interface. Three
parallel interface modes provide flexibility and allow users a
trade-off among speed, power and bus width. Pixel data
employs a double data rate scheme, allowing video data to be
transferred using both clock edges. Applications Laser-based Pico Projectors High-speed, triple-output laser diode driver supporting up to
720-pixel HD resolution Fast output switching speeds with pulse rise/fall times of
1ns to 2ns for crisp pixels Intersil patented laser voltage sampler function provides
dynamic power management capability to dramatically
minimize system power Intersil patented SmartLinearizerв„ў DAC feature provides a
linear transfer function (input video code to green laser
output), eliminating the need for DSP controller processing …
