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
