  • Programmable Crystal Oscillators with Sub-ps Jitter and Multiple Frequency Capability
    is only possible when they are sealed. in clean, dry, hermetic packages. Oscillator packages today are smaller; stabilities are tighter, and frequencies are. higher. Yet, quartz crystals are still fabricated in much the same way that they were in. 1943. Each new frequency requires a new crystal to be cut
