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.
