* Each output line is same length.
* To measure the disable current, OE pin is connected to GND.
2) Measurement condition
(1) 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.
(2) By-pass capacitor 1 (approx. 0.01 μF to 0.1 μF) places closely between Vcc and GND.
(3) By-pass capacitor 2 (approx. 10 μF) places closely between power supply terminals on the board.
(4) Use the current meter whose internal impedance value is small.
(5) Power supply
• Start up time (0 V→90 %Vcc) of power source should be more than 150 μs
• Impedance of power supply should be as low as possible.

Note:
OE pin = HIGH or “Open” : Specified frequency output.
OE pin = LOW : Output is high impedance
In order to achieve optimum jitter performance, it is
recommended that the capacitor (0.1 μF + 10 μF)
between Vcc and GND pin should be placed as
close to the Vcc pin as possible.
