True sinewave VCXO delivers ultra-low noise floor between 50 MHz and 125 MHz

Crystek Crystals Corporation has launched the CVSS-945 — a true sinewave voltage controlled crystal oscillator (VCXO) providing -172.9 dBc/Hz noise floor at 1 MHz offset and ±20 ppm minimum APR pullability.

This high-performance VCXO is available in the industry standard 9 x 14 mm SMD package and is engineered to MIL-STD-883 and MIL-STD-202 specifications.

The CVSS-945 VCXO generates frequencies between 50 MHz and 125 MHz, with output level of +5 dBm min into 50 Ohms and harmonics lower than -25 dBc. The CVSS-945 consumes 30 mA maximum current at 5.0 V and generates no sub-harmonics.

The CVSS-945 is ideal in PLL (phase locked loop) applications where the requirement is translating from 10 MHz to 100 MHz, as an example. For industrial and other rugged uses extended temperature operating range of -40°C to +85°C and other custom specifications are also available.
