Space Oven Controlled Crystal Oscillator RK 408 108 Stability class OCXO For this product, full and detailed spcifications can be delivered on request. Spcifie request can be addressed to RAKON [email protected] Product Description This Low Noise Space OCXO is designed for Clocks, Navigation and Positioning Systems. It is used in such applications as GPS receivers, digital cards, onboard calculators, down and up converters, synthesizers. This frequency source is featured by remarkable overall frequency stability vs. temperature range up to ±10 ppb under vacuum, ± 100 ppb per year, power consumption at steady state of 2W under vacuum. The RK408 is manufactured in accordance with MIL-PRF-55310 (Class 1, type 4, level S), is available in different packages in a volume of 40x50x20mm. Features ITAR-Free Low phase noise Frequency Range: 10 MHz to 125 MHz Supply Voltage: +5V to +12V Multi-package Warm up Consumption: 5 W max Steady state Consumption: 2 W under vacuum and 3W under atmospheric pressure Frequency Stability vs. Operating Temperature Range: ±10 ppb under vacuum Ageing : ±0.20 ppm over 30 years typical at 10 MHz Output Wave Form : sine 50 Ohms Output Level : from 10 to 12 dBm Component selected as per ECSS-Q-ST-60C Materials selected as per ECSS-Q-70 Manufacturing in accordance with: o MIL-PRF-55310 (Class 1, type 4, level S) o ECSS-Q-ST-70-08C and ECSS-Q-ST-70-38C Applications 驕 Transponders Onboard calculators Օ GPS receivers Synthesizers Օ Navigation FGU Օ Converters Spcifications 1.
