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. 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 GENLOCK PLL 1 IDT9173B REV A 092308 datasheet pdf - http://www.DataSheet4U.net/ 1 page IDT9173B VIDEO GENLOCK PLL CLOCK SYNTHESIZER DC Electrical Characteristics Unless stated otherwise, VDD = 5 V ±5%, Ambient Temperature 0 to +70° C Parameter Symbol Conditions Min.
