CVCO55BE-0510-0770

Overview

The CVCO55BE-0510-0770 is a voltage-controlled oscillator from Crystek Corporation designed for high-frequency applications. It operates within a frequency range of 510 MHz to 770 MHz, centered around a nominal output of 640 MHz. The device requires a 5V supply voltage and draws a typical operating current of 25 mA. It features a tuning slope of 4 MHz/V with a control voltage range of 1 V to 17 V. The output power is specified at 4 ± 2 dBm, while the secondary harmonic suppression is -15 dBc. Phase noise performance reaches -100 dBc/Hz at 1 kHz offset. The component is housed in a QFN-16 package measuring 12.70 x 12.70 mm with a height of 3.81 mm, suitable for surface mount technology, and functions reliably between -40°C and +85°C.
