MK9173-01CS08

VIDEO GENLOCK PLL
The MK9173-01/-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 theimplementation 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.
The MK9173-01/15 is pin and function compatible to the AV9173-01/15. For new video genlock designs, please refer to the ICS673-01, ICS1522 or ICS1523.
