Overview

PRELIMINARY DATASHEET VIDEO GENLOCK PLL Description The IDT9173B 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 IDT9173B 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 IDT9173B is the implementation of a video genlock circuit.
Because of this, the IDT9173B input...
