AXTAL’s OCXOs Offer Ultra-Low Noise and Jitter Over Wide Frequency Ranges

AXIOM ULN OCXO’s offer ultra-low, close-in phase noise and noise floor and reduced jitter;

Ideal for radar, communication, and RF measurement systems.

Q-Tech Corporation, a leading global supplier of space-qualified crystal oscillators and high-performance frequency control systems, announces the availability of the AXIOMline of ultra-low noise (ULN) oven-controlled crystal oscillators (OXCOs).

Designed and manufactured by Q-Tech’s German affiliate, AXTAL, the benefits of the AXIOM ULN OCXO’s ultra-low phase noise (close-in and noise floor) are higher resolution for radar systems, better quality and more transmissible information for communications systems, and improved accuracy and lower measurement limits for RF measurement systems. Ultra-low phase noise OCXOs can be customized to achieve near-ideal multiplication and, by allowing the use of various noise-cancellation techniques, they can transfer noise levels up to the GHz range. They also reduce jitter—an essential consideration in these applications—with RMS jitter values of <50 fs for integration ranges of 10 Hz ~ 30 MHz.

The AXTAL line of ultra-low phase noise AXIOM OCXOs comprises 16 devices, including the AXIOM75ULN and AXIOM5050ULN (80 to 160 MHz) and the multiple-output AXIOM2700 (50 MHz to 7.0 GHz), all offering exceptional phase noise. At lower frequencies (non-multiplied), the AXIOM ULN OCXOs can obtain <-140 dBc/Hz @ 100 Hz offset and a noise floor down to -185 dBc/Hz. These benefits make ultra-low phase noise AXIOM OCXOs ideal for sophisticated applications requiring frequency generation from MHz to GHz. “AXTAL’s ‘ULN’ devices provide a selection of OCXOs operating over broad frequency ranges with the option of creating fully customizable modules using frequency multiplication and/or PLL techniques,” said Henry Halang, AXTAL’s Managing Director. “With the ability to generate signals at GHz levels, ULN OCXOs offer our customers maximum design flexibility and superior performance.”
