MK9173-01 MK9173-15 Video Genlock PLL General Description The MK9173-01 and MK9173-15 provide the analog PLL circuit blocks to implement a frequency multiplier. Because the device is configured to use an external divider in the PLL clock feedback path, a large divider can be used to result in a large frequency multiplication ratio. This is useful when using a low frequency input clock to generate a high frequency output clock. The MK9173-01/15 contains a phase detector, charge pump, loop filter, and voltage-controlled oscillator (VCO). The ICS674-01 can be used as the external feedback divider. A common application of the MK9173-01/-15 is the implementation of a video genlock circuit. Because of this, the MK9173-01/-15 inputs operate on the negative-going clock edge. The MK9173-01/15 is pin and function compatible to the AV9173-01/15. Please refer to page 4 regarding performance differences. For new video genlock designs, please refer to the ICS673-01, ICS1522 or ICS1523.
