MEASUREMENT CIRCUITS

Measurement Circuit 1

Measurement Circuit 2

Measurement Circuit 3

500mVp-p, sine wave

C1: 0.01µF

R1: 49.9

Ω

Note. Connect 0.01µF and approximately 10µF bypass capacitors between supply (VCC, VCC2) and

GND. Note that the 0.01µF capacitor should have circuit wiring as short as possible.

R1: 49.9

Ω

Note 1. Connect 0.01µF and approximately 10µF bypass capacitors between supply (VCC, VCC2) and

GND. Note that the 0.01µF capacitor should have circuit wiring as short as possible.

Note 2. The recommended differential probe used for measurement should have 5GHz analog

bandwidth,

≥ 50kΩ impedance, and < 1pF capacitive load.

Note 3. If common-mode noise becomes a problem, a DC decoupling capacitor (approximately 1000pF)

and terminating resistor matching the common-mode signal should be connected to the output

center tap.
