Because we use a PLL technology, there are a few cases that the jitter value will increase when SG-8002 is connected to another

PLL-oscillator.

In our experience, we are unable to recommend these products for the applications such as telecom carrier use or analog video

clock use. Please be careful checking in advance for these application (Jitter specification is Max.250 ps/CL=15 pF)

We do not recommend inserting filters or other devices in the power supply line as the counter measure of EMI noise reduction.

This device insertion might cause high-frequency impedance high in the power supply line and it affects oscillator stable drive.

When this measure is required, please evaluate circuitry and device behavior in the circuit and verify that it will not affect oscillation.
