Space Oven Controlled Crystal Oscillator RK 407 10-7 Stability class OCXO For this product, full and detailed specifications can be delivered on request. Specific request can be addressed to RAKON [email protected] The RK407 is a Space OCXO dedicated to Telecom payloads as it is in the 10 stability class over the temperature range with an overall frequency drift less than 2ppm over 18 years and available with a short lead time. It is designed for clocks, signal generation applications, transponders, GPS receivers, digital cards, board calculators, down and up converters, and synthesizers. This frequency source is a good trade-off between overall frequency stability and power consumption. It is manufactured in accordance with MIL-PRF-55310 (Class 1, type 4, level S) and is available in a flat pack package (25x25x17mm). Features Wide frequency range: 10MHz-130MHz Standard Frequencies: 10, 38-45, 90-110, 120-130MHz Low consumption: 0.65 W Supply Voltage : +5V or +12V Warm up Consumption : 2 Watt Overall Frequency Stability vs. Operating Temperature Range ± 0.5ppm under vacuum Ageing :± 1 ppm over 18 years typical Output Wave Form : sine 50 Ohms Compatible with Flat pack TCXO pin-out Component selected as per ECSS-Q-ST-60C Materials selected as per ECSS-Q-ST-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 Transponders GPS receivers Navigation Converters Onboard calculators Synthesizers FGU Specifications Environmental conditions Parameters Operating Temperature Switch-on Temperature Non-Operating Temperature Random Vibration Sine Vibration Electrical interface Conditions/remarks Min Nom Max Unit TOp -40 25 70 °C TSo -40 85 °C TNOp -55 125 °C Level as per MIL-STD-202 Method 214 20 to 100 Hz : +6dB/oct 100 to 1000 Hz : 2.6 g²/Hz 1000 to 2000 Hz : -6dB/oct Overall : 61grms Parameters Power supply Load Impedance Reference voltage Control voltage Conditions/remarks Min Nom Max Unit Option 1 (12V) 11.40 12 12.60 V Option 2 (5V) 4.75 5 5.25 V 45 50 55 Supply voltage 5.4 6 6.6 V option 1 Supply voltage 2.85 3 3.15 V option 2 Only with Freq adj 0 Vrefnom V option 2 Level as per MIL-STD-202 Method 204, Condition D (20G) Mechanical shock as per MIL-STD-202, Method 213 : half sine with a peak acceleration of 3000g for duration of 0.3msec Total Ionizing Dose of 100 kRad, low dose rate (36 to 360 rad/h) Specifications subject to change without notice 1/2
