ULTRA-LOW JITTER VCXO | HIGH PERFORMANCE Issue: C, 17 May 2023 Specifications are subject to change without notice Copyright © 2021 to 2023, Rakon Limited. All rights reserved Page 1 of 2 sales@rakon.com RVX1490U The RVX1490U is an ultra-low phase noise VCXO featuring a superior phase noise floor of -173 dBc/Hz (@153.6 MHz), RMS phase jitter 12 fs (12 kHz to 20 MHz ). It is available in frequencies ranging from 38.4 to 245.76 MHz. The excellent phase noise performance enables the oscillator to improve the data transmission capabilities of optical and radio networks. The RVX1490U uses a high -Q (quality) factor quartz resonator with 3rd overtone technology together with Rakon's proprietary electric circuit design to deliver outstanding phase noise performance. It has an excellent all- causes frequency stability of ±20 ppm over a wide temperature range of -40 to 95°C (inclusive of 20 years of all causes stability). The RVX1490U comes in a low profile 14 x 9 mm SMD package making it suitable for a wide variety of timing applications. Apart from the next generation 5G radios, the device also targets satellite ground stations , test and measurement equipment, custom telecommunication equipment and optical communication equipment designs, all of which require very low phase noise reference clocks.
