OVERALL CAPABILITY
ABLNO-EVAL; Frequency Divider Evaluation Board shown in figure (1) is designed to facilitate engineering evaluation of Abracon’s Ultra Low Noise – ABLNO series of fixed clock and voltage controlled crystal oscillators.
Further, there is a provision through the RF_IN SMA Connector to supply any other oscillator signal between 10MHz
and 200MHz; if ABLNO series is not being characterized.
This Evaluation Board is ideal to conduct the following measurements:
• Phase Noise and rms jitter for ÷1, ÷2, ÷4 and ÷8 frequency outputs
• Frequency Pull Characteristics of the ABLNO by using the Vc port as the control voltage
• Frequency Stability over operating temperature (-40ºC to +85ºC)
Figure (1)
Designers who are interested in using the ABLNO as an Ultra Low Noise platform device to generate additional
Low Noise frequencies will find this Evaluation Board to be of exceptional value. Abracon has implemented Ultra
Low Noise ÷2, ÷4 and ÷8 circuitry on this board, that can also be incorportated in end-customer solutions; please
contact [email protected] for additional details.
Tpycial Phase Noise and jitter peformance in ÷1, ÷2, ÷4 and ÷8 modes is depicted in section 2.0.

Functionality
Input a 10MHz to 200MHz oscillator signal into this SMA
connector for evaluation…see Note #5
When characterizing the ABLNO series of VCXO’s, apply
control voltage to this port to characterize frequency pull
This port simultaneously biases the ABLNO Oscillator
and the divider scheme (+3.3V ±5%) …..see Note #4
Either ABLNO or RF_IN frequency is divided down by 1,
2, 4 or 8 and is present at this port
If the tab is moved to the “up position (UP)”, RF_IN
signal is selected. If the tab is moved to the “down
position (DN)”, ABLNO signal is selected
If the tab is moved to the “up position (UP)”, RF_IN
signal is divided down by 2 and is present at RF_Out
If the tab is moved to the “up position (UP)”, RF_IN
signal is divided down by 4 and is present at RF_Out. S2
should also be in the “up position (UP)”… please see truth
table #1
If the tab is moved to the “up position (UP)”, RF_IN
signal is divided down by 8 and is present at RF_Out. S2
& S3 should also be in the “up position (UP)”… please

Note # 2: All four switches are shipped with yellow protective tape on top, please remove before use
Note # 3: To evaluate Abracon’s ABLNO Crystal Oscillator, please solder it down in the section outlined
with a rectangle and labeled ABLNO. Please follow the orientation shown in figure (3) below.
Figure (3)
Note # 4: VDD Port biases both the ABLNO device, as well as the divider circuitry. Since ABLNO’s
VDD range is +3.3V ±5%, the recommended VDD range while evaluating ABLNO oscillators is
+3.135V to +3.465V. However, since the divider circuitry can be biased between +1.8V &
+5.5V, while evaluating RF_IN external signal; lower or higher biasing voltage can be used, as
long as the peak-to-peak signal from the RF_IN port does not exceed the bias voltage (VDD).
Note # 5: RF_IN port expects a LVCMOS signal. If a clipped Sinewave or Sinewave signal with lower
amplitude is used; it might be necessary to square-that-up. There is a provision above (S1) to
add a buffer to achieve this. Please contact [email protected] .
