Oven Controlled Crystal Oscillators (OCXO’s) Description: The EX-240 Series offers a ruggedized hybrid thick film construction in a low EX-240 (EMXO™) profile, hermetically sealed 16 pin DDIL package, which can withstand severe environmental conditions. This product series utilizes VI’s EMXO TM technology resulting in excellent stability performance and fast warm-up with low power consumption. Features: * Temperature Stability: to ±1 x 10-8 over 0°C to +50°C * Acceleration Sensitivity: < 1 x 10 -9 / g Total Gamma * Low power consumption: < 0.7 W @ +25°C * Shock: 1,000g’s peak, 0.5 ms * Vibration: 20g peak to 2 kHz (Sine), 30 Grms overall to 2 kHz (Random) Performance Characteristics Parameter Characteristics Frequency Range: Package Size: Supply Voltage: Supply Current (Steady State): Turn-on Current: Output Type: Level "0" and "1": 10 to 20.48 MHz See next page for drawings and dimensions (reduced height option is available) (C) +5 Vdc ±5%, (D): +3.3 Vdc ±5% <140 mA @ +25°C , <220 mA @ -40°C with +5V supply <210 mA @ +25°C , <330 mA @ -40°C with +3.3V supply (reduced current option is available) <500 mA with +5Vdc supply, <600 mA with +3.3 Vdc supply (A) HCMOS <0.4 Volts, >0.9 Vdd Rise/Fall Time (10-90%): <7 ns Symmetry (Duty Cycle): 50/50 ±10% (at 50% Vdd) Output Type: (H) +3 dBm minimum into 50 ohms Harmonics: - 20 dBc Spurious: - 60 dBc Temperature Stability: B-108 = ± 10 ppb over 0°C to +50°C C-208 = ± 20 ppb over 0°C to +70°C (Note: Tighter stabilities and wider temperature ranges are available, please consult factory.)
