All rights reserved Page 1 of 4 Contact Us RK508NS The RK508NS is a NewSpace OCXO with excellent phase noise performance and low power consumption. It features Rakon’s proven and highly successful proprietary Mercury+™ Integrated Circuit (IC) technology. Providing a Total Ionizing Dose (TID) resistance of up to 30 krad, the MercuryR™ (Rad-Hard) ASIC was specifically developed to withstand the harsh radiation environment encountered in Traditional S pace and NewSpace applications. Key advantages of IC -OCXOs over discrete oscillators are the smaller package size, lower power consumption, lower cost, shorter lead times and increased reliability b ecause of the reduced number of components. The RK508NS is designed for lifetime missions of up to 12 years. The standard f requencies of the RK508 NS are 10 MHz , 10.23 MHz, 10.24 MHz, 40 MHz and 100 MHz. It is housed in a small, low -profile, hermetically sealed package of 22 x 22 x 13 mm. This means performance does not change under atmospheric pressure (atm) or vacuum. All testing is done at atmospheric pressure. The RK508NS can be adapted to large package sizes to fit specific PCB boards’ layouts and requests.
