The O-CDFEXYZXX-X-X-10MHz/100MHz from NEL Frequency Controls is an Ultra Low Phase Noise Dual Frequency OCXO that operates at 10 MHz and 100 MHz. The Lower frequency OCXO provides excellent frequency stability of ±2 ppb over temperature, low time aging of 0.25 ppb/day, supply and load variations, as well as exceptionally low phase noise of-145 dBc/Hz at 10 Hz offset, and short-term stability (Allan Variance). Whereas, at 100 MHz the OCXO provides an ultra-low phase noise of -180 dBc/Hz at 100 kHz and high output power of 13 dBm. It operates over a supply voltage of 4.75 to 5.25 V and provides sinewave at the output. This OCXO is available in a hermetically sealed drop-in package that measures 36 x 27 mm and is ideal for instrumentation, synthesizers, radar, and telecommunication equipment applications. The device can be customized as per the users requirement.
