Description

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 frequency locked high speed output. Stored in the device are the multipliers for 16 combinations of popular frequencies for analog and digital TV and set-top box systems.
