PERFORMANCE TUNING INDUCTOR VALUE SELECTION
Please refer Abracon's `Tuning Assistance' software automatically calculate optimum inductor values your application. addition, chart below could used reference quick inductor value selection. Please note that inductor values mentioned table below, when using `Tuning Assistance' derived based parasitic values Abracon's evaluation board. performance enhancement your custom board design, please follow following instruction: special test modes "VCO Max" "VCO Min" determine optimum inductor value. "VCO Max" represents high range "VCO Min" represents range. output frequency "VCO Max" "VCO Min" test modes VCO/16. This means that output frequencies around crystal frequency that will used. optimum inductor value where target crystal frequency closest middle between "VCO Max" "VCO Min" output frequencies. this case will lock middle tuning range with maximum margin either side.

LAYOUT RECOMMENDATIONS

ABV806X (VCXO)
LAYOUT CONSIDERATIONS PERFORMANCE OPTIMIZATION
following guidelines assist with performance optimized design: Keep traces ABV80 short possible, well keeping other traces away from possible. Place crystal close possible both crystal pins device. This will reduce cross-talk between crystal other signals. Separate crystal traces from other signals PCB, allow ample distance between crystal traces. Place 0.01µF~0.1µF decoupling capacitor between GND, component side PCB, close pin. recommended place this component backside PCB. Going through vias will reduce signal integrity, causing additional jitter phase noise. highly recommended keep traces short possible. Please contact Abracon application note design outputs driving long traces Gerber files ABV80 layout.
