These precision OCXOs are available in a variety of compact housings for output frequencies to 120 MHz with low phase noise.
Those searching the 2013 IMS show floor for precision sources will find several new oven-controlled crystal oscillators (OCXOs) on display at 2013 IMS booth No. 918, for CTS Electronic Components. The company’s models 122, 144, 148 OCXOs will be on display for the first time in Seattle, suitable as reference oscillators for a wide range of fixed and portable communications systems. The oscillators are designed for low power consumption (less than 1 W) in compact housings. For example, model 122, which is available with output frequencies from 8 to 100 MHz, is supplied in a 20 x 20 mm housing. It is capable of maintaining frequency stability of ±2 ppb at temperatures from -10 to +60°C and ±0.2 ppb/day aging for a 10-MHz source. Model 144 is housed within a TO-8 package and available with output frequencies from 8 to 120 MHz and phase noise floor as low as -170 dBc/Hz at 100 MHz. The model 148, based on a precision stress-compensated (SC) crystal, is also supplied in a TO-8 package and available in frequencies from 8 to 100 MHz.
