... 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 ...

... External Components/Crystal Selection The MK1573 requires a minimum number of external components for proper operation. A 0.1µF low leakage capacitor (see Capacitor Selection on following page) should be connected between CAP1 and CAP2 as close to the chip as possible. A high quality ceramic capacitor is recommended. A decoupling capacitor of 0.1µF must be connected between VDD and GND pins (pins 2 and 3, 5 and 7) close to the chip, and 33 terminating resistors can be used on clock outputs with traces longer than 1 inch ...

... CLK2 may benefit from a series 33 resistor connected close to the pin (not shown). Video Clock Multipliers/Accuracies In the table on page 2 are the actual multipliers stored in the MK1573-02 ROM, which shows that the accuracies are within one ppm for the output clocks.

... Clock Waveforms In addition to generating the video clock on CLK1 (pin 10), the MK1573 also outputs the recovered HSYNC clocks. On certain selections, a double speed recovered HSYNC clock is also available. These recovered clocks will have lower jitter than the HSYNC input due to the filtering action of the PLL. The jitter spectrum of the recovered clocks will be reduced at frequencies higher than the loop bandwidth ...
