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 inputs operate on the negative-going clock
edge.
The IDT9173B is pin and function compatible to the
AV9173-01/15.
