VCXOs Cut Noise from 131 to 200 MHz

Available for frequencies from 131 to 200 MHz, model CVHD-952 is a HCMOS low-phase-noise voltage-controlled crystal oscillator (VCXO) with low phase noise. Designed for voltage supplies of +3.30 VDC, the oscillator exhibits phase noise of -70 dBc/Hz offset 10 Hz from the carrier, -148 dBc/Hz offset 10 kHz from the carrier, and a noise floor of -150 dBc/Hz. Typical jitter is 0.5 ps at all offset frequencies. Standard units have an operating temperature range of 0 to +70°C; as an option, sources can be supplied for an operating temperature range of -40°C to +85°C. The VCXO is supplied in a surface-mount-device (SMD) package measuring 9 × 14 mm.
