Fort Myers, Fla. Crystek Crystals Corp. has launched its latest high-performance true sinewave voltage controlled crystal oscillator (VCXO) in a surface-mount 9 x 14-mm package. The new CVSS-940 exhibits a low phase noise of 150 dBc/Hz and ±50 ppm minimum absolute pull range.
The new VCXO generates frequencies between 77.760 MHz and 500 MHz with an output level of 0 dBm minimum, 50 ohms and harmonics lower than -20 dBc. The device consumes 25 mA typical and 30 mA maximum current at 3.3 volts. It has low or no sub-harmonics depending on frequency due to the use of inverted mesa (high frequency fundamental crystal) technology.
The VCXO may be specified for telecommunications applications such as 10-Gigabit Ethernet, broadband networks, SONET/SDH/DWD, network/switch, and ATM communications. For industrial and other rugged uses, an extended temperature operating range of -40°C to 85°C is available along with other custom specifications.
VCXO pricing start at $24 ea. in volume, depending on specification. The device is also available directly from Mouser Electronics (www.mouser.com), which maintains a large selection of Crystek's high-performance devices.
