Applications
● GPF and GPW uses high-Q fundamental crystals and low jitter multiplier circuits.
● GPF offers < 1 ps phase jitter at only a fraction of the cost of a high frequency
fundamental crystal VCXO. GPW series has moderate jitter at a low cost.
General specifications of GPF and GPW only , at Ta=+25°C , CL=15pF
