Jitter specifications and characteristics chart
■
PLL-PLL connection
The SG-8002 series contains a PLL circuit and there are a few cases where the jitter value may be increased when this product
is connected to another PLL oscillator (cascading connection). We do not recommend this series for analog video clock use and
telecommunication synchronization. Please check in advance if the SG-8002 series jitter is acceptable to your application.
(Jitter specification of the SG-8002 series is max.250 ps/CL=15 pF)

Remarks on noise management for power supply line
It is not recommended to insert filters or other devices in the power supply line as a counter measure for EMI noise reduction.
This may cause high-frequency impedance of the power supply line and negatively affect stable oscillation.
When using this measure please evaluate the circuitry and device behavior in the circuit to verify and effects on oscillation.
Start up time (0 % V
CC
to 90 % V
CC
) of power source should be more than 150
s.
