General Description

The AV9173-01 provides the analog circuit blocks required for implementing a video genlock dot (pixel) clock generator. It contains a phase detector, charge pump, loop filter, and voltage-controlled oscillator (VCO). By grouping these critical analog blocks into one IC and utilizing external digital functions, performance and design flexibility are optimized as are development time and system cost.

Features

• Phase-detector/VCO circuit block

• Ideal for genlock system

• Reference clock range 25 kHz to 1 MHz for full output clock range

• Input clocks down to 12 kHz possible with restricted output conditions (see Table 1)

• Output clock range 1.25 to 75MHz

• On-chip loop filter

• Single 5 volt power supply

• Low power CMOS technology

• Small 8-pin DIP or SOIC package
