The ABV806X is a monolithic low jitter and low
phase noise VCXO, capable of 0.4ps RMS phase
jitter and PECL or LVDS outputs, covering a wide
frequency output range up to 640MHz. It allows the
control of the output frequency with an input voltage
(VCON), using a low cost crystal.

All SEL pads have internal pull-ups (default value is ‘1’). Bond to GND to set to 0.
* Special Test Modes to help selecting the inductor value for the target output frequency.
PERFORMANCE TUNING & INDUCTOR VALUE SELECTION
Please refer to Abracon’s ‘Tuning Assistance’ software to automatically calculate the optimum inductor values for
your application. In addition, the chart below could be used as a reference for quick inductor value selection.
Please note that the inductor values mentioned in the table below, or when using the ‘Tuning Assistance’ are
derived based on the parasitic values of Abracon’s evaluation board. For performance enhancement of your
custom board design, please follow the following instruction:
Use the special test modes “VCO Max” and “VCO Min” to determine the optimum inductor value. “VCO Max”
represents the high end of the VCO range and “VCO Min” represents the low end of the VCO range. The output
frequency in the “VCO Max” and “VCO Min” test modes is VCO/16. This means that the output frequencies are
around the crystal frequency that will be used. The optimum inductor value is where the target crystal frequency
is closest to the middle between the “VCO Max” and “VCO Min” output frequencies. In this case the VCO will lock
in the middle of its tuning range with maximum margin on either side.

device and affect product reliability. These conditions represent a stress rating only, and functional operations of the device at these or any other
conditions above the operational limits noted in this specification is not implied.

PCB LAYOUT CONSIDERATIONS FOR PERFORMANCE OPTIMIZATION
The following guidelines are to assist you with a performance optimized PCB design:
- Keep all the PCB traces to ABV80 as short as
possible, as well as keeping all other traces as
far away from it as possible.
backside of the PCB. Going through vias will
reduce the signal integrity, causing additional
jitter and phase noise.
- Place the crystal as close as possible to both
crystal pins of the device. This will reduce the
cross-talk between the crystal and the other
signals.
- Separate crystal pin traces from the other signals
on the PCB, but allow ample distance between
the two crystal pin traces.
- It is highly recommended to keep the VDD and
GND traces as short as possible.
- Please contact Abracon for the application note
on how to design outputs driving long traces or
the Gerber files for the ABV80 layout.
- Place a 0.01µF~0.1µF decoupling capacitor
between VDD and GND, on the component side
of the PCB, close to the VDD pin. It is not
recommended to place this component on the
