VFJC Crystal Oscillators HCMOS 3.3V 3.2X2.5mm Surface Mount 2 MHz to 50 MHz Features Description Wide frequency range with 3.3V supply High speed-Low jitter CMOS output with tristate Small SMD package-3.2X2.5mm Extra low profile for slimline applications Stability options: 100, 50 or 25ppm Commercial or industrial temperature range Rugged, hermetic package for automated assembly Valpey Fisher's JC surface mount crystal oscillator provides waveforms for clocking HCMOS and TTL circuits. The new 3.2X2.5mm footprint package provides the performance of larger oscillators with 75% reduction in board space over other industry standard packages. Low jitter output signals are generated via the use of hi-Q fundamental or overtone miniature quartz resonators. They are ideal for space critical portable or hand-held equipment, while their tight tolerance and low noise performance makes them also the ideal choice for high data rate telecom applications. The wide range of frequencies from 2 to 50MHz, many stability options, 3.3 volt supply, and industrial temperature ranges, makes this model attractive for any application requiring extreme size reduction. Tape and reel packaging is standard.
