True sinewave clock oscillators for low-noise RF performance introduced by Crystek Crystals Corp.
Jan. 9, 2014
FORT MYERS, Fla., 9 Jan. 2014. Crystek Crystals Corp. in Fort Myers, Fla., is introducing the CCSS-945 true sinewave clock oscillator (XO) for RF and microwave applications requiring ultra-low noise performance similar to more expensive OCXO crystal oscillators.
The CCSS-945 provides -170 dBc/Hz noise floor at 1 MHz offset. The close-in phase noise performance is an -105 dBc/Hz typical at 10 Hz offset.
The device is available in the industry standard 9-by-14-millimeter SMD package. The device is designed to MIL-STD-883 and MIL-STD-202 specifications. Versions for an extended-temperature operating range of -40 to 85 degrees Celsius and other custom specifications also are available.
The CCSS-945 clock oscillator generates frequencies between 10 MHz and 125 MHz, with output level of +5 dBm min into 50 Ohms and harmonics lower than -25dBc. The CCSS-945 consumes 30 milliamps maximum current at 5 volts and has no sub-harmonics.
