MK1573-02 Overview
The MK1573 GenClock™ provides genlock timing for video overlay systems. The device accepts the horizontal sync (HSYNC) signal as the input reference clock, and generates a frequencylocked high speed output. Stored in the device are the multipliers for 16 binations of popular frequencies for analog and digital TV and set-top box systems.
