3) Measurement condition
A) Oscilloscope
•Bandwidth should be 5 times higher than DUT’s output frequency (4 GHz).
•Probe ground should be placed closely from test point and lead length should be as short as possible.
B) By-pass capacitor 1 (approx. 0.01 μF to 0.1 μF) places closely between Vcc and GND.
C) By-pass capacitor 2 (approx. 10 μF) places closely between power supply terminals on the board.
D) Use the current meter whose internal impedance value is small.
E) Power supply
• Start up time (0 Vg90 %Vcc) of power source should be more than 150 μs and
slew rate should be less than 19.8 mV/μs.
• Impedance of power supply should be as low as possible.

To maintain stable operation, provide a 0.01uF to 0.1uF
by-pass capacitor at a location as near as possible to the
power source terminal of the crystal product (between Vcc
- GND).

8.Example of schematic layout
This figure shows an example of this product’s application schematic.
As with any high speed analog circuitry, the power supply pins for this device are vulnerable to
noise. In order to achieve optimum jitter performance, power isolation with filter device is
required for power supply pins.
In order to achieve best performance of the power isolation filter, it is recommended that the filter
composing devices is placed on the device side of the PCB as close to the power pins as
possible. The component value of this filter is just an example, it may have to be adjusted.

* By-pass capacitor (approx. 0.01 μF to 0.1 μF) places closely between Vcc and GND.
* By-pass capacitor (approx. 10 μF) places closely between power supply terminals on the board.
* Please design the two output lines by characteristic impedance 100 Ω and same length, and try
to make the output lines as short as possible.
