CRYSTEKCRYSTAL CVHD-950X

CCHD/CVHD-950
Ultra-Low Phase Noise
Oscillators
Model CCHD/CVHD-950 is a 50Mhz to 125Mhz CMOS Clock Oscillator or
CMOS Voltage Controlled Crystal Oscillator. High Q crystal and 3rd overtone
technology provides Ultra-Low Phase Noise and Low-Jitter performance with a
CMOS output. Features include -162dBc/Hz phase noise floor with 3.3Vdc input
voltage, -40 to +85C operating temperature, and 9x14 mm SMT package. The
oscillator has no sub-harmonics.
Applications include High Definition TV, Low Phase Signal Sources, Test and
Measurement, and Avionics.
