Description

The MK1707 generates a low EMI output clock from a clock input. The part is designed to dither the LCD

interface clock for flat panel graphics controllers. The device uses ICS’ proprietary mix of analog and digital

Phase Locked Loop (PLL) technology to spread the frequency spectrum of the output, thereby reducing the

frequency amplitude peaks by several dB.
