IDT9173B - VIDEO GENLOCK PLL

Datasheet Summary

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.

Features

Phase-detector/VCO circuit block.
Ideal for genlock system.
Reference clock range 12 kHz to 1 MHz for full output clock range.
Output clock range of 1.25 to 75 MHz (-01), and 0.625 to 37.5 MHz (-15). See “Allowable Input Frequency to Output Frequency” table for conditions.
On-chip loop filter Single 5 V power supply Low power CMOS technology 8-pin SOIC package Block Diagram http://www. DataSheet4U. net/ IDT™ VIDEO GEN.

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 inputs operate on the negative-going clock edge.
