This product series utilizes VI’s EMXOTM 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 Frequency Range: 10 to 20.48 MHz Package Size: See next page for drawings and dimensions (reduced height option is available) Supply Voltage: (C) +5 Vdc ±5%, (D): +3.3 Vdc ±5% Supply Current (Steady State): <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) Turn-on Current: <500 mA with +5Vdc supply, <600 mA with +3.3 Vdc supply Output Type: (A) HCMOS Level "0" and "1": <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 D-308 = ± 30 ppb over -20°C to +70°C ranges are available, please consult factory.) F-508 = ± 50 ppb over -40°C to +85°C Aging (10MHz Typical): <1x10-9 /day average, <1x10-7 / year average, <1x10-6 /10 years Short-Term Stability (Allan Deviation): <1x10-10, 0.1 seconds to 10 seconds Phase Noise: Offset Phase Noise (typical at 10 MHz, Static Condition) 10 Hz -100 dBc/Hz 100 Hz -130 dBc/Hz 1 kHz -140 dBc/Hz 10 kHz -145 dBc/Hz 100 kHz -150 dBc/Hz Frequency vs. Supply: <2.5x10-9 per percent change Warm-up (Restabilization): Standard Optional (consult factory) (frequency relative to that 1 hour after turn-on, <±1x10-6 60 seconds 45 seconds following 24 hours off time, at +25°C) <±1x10-7 120 seconds 90 seconds Electrical Frequency Adjust: >± 1ppm range with 0 to Vdd input voltage Acceleration Sensitivity: 1x10-9/g Total Gamma, standard (10 MHz) 5x10-10/g available at 10 MHz (consult factory) Parameter Characteristics |
