Intersil ISL78365ARZ-T7A

Description
The ISL78365 is a high-speed, quadruple output Laser Diode Driver (LDD) designed for high-speed RGB/RGGB laser scanning projection systems. Each output driver channel consists of independent threshold and color DACs for greater laser control and flexibility. Separate scale DACs allow independent scaling of both threshold and color DAC output values to control the projector brightness or provide simple Automatic Power Calibration (APC) for laser-based systems. Pixel data information is transferred through the LDD's high-speed 10-bit parallel video interface. There are two parallel interface modes to allow three or four color pixel data to be entered efficiently. Pixel data employs a double data rate scheme, allowing video data to be transferred using both edges of the clock.
