EURO QUARTZ HGXO OSCILLATORS High Shock SMD Crystal Oscillator 460kHz to 50MHz FEATURES Frequency Range 460kHz to 50MHz Mechanical shock survivability up to 100,000g Supply voltage from 0.9V to 5.0Volts available Low EMI emission Hermetically sealed package Low acceleration sensitivity available Full MIL testing to MIL-PRF-55310 available SM1 and SM5 versions are pB free OUTLINE & DIMENSIONS DESCRIPTION HGXO oscillators are miniature, surface mount units that can survive extremely high shocks, up to 100,000g. The design consists of a hermetically-sealed high shock crystal and a CMOS compatible integrated circuit housed in a SMD 7.5mm x 5.0mm ceramic package. SPECIFICATION Specifications are typical at 25°C unless otherwise indicated. Tighter specifications are available, contact Euroquartz technical sales. Supply Voltage: +0.9V to +5.0 Volts Calibration Tolerance: From ±10ppm Frequency Stability over Operating Temperature Range** Commercial (0° ~ +70°C): From ±10ppm Industrial(-40° ~ +85°C): From ±20ppm Military (-55° ~ +125°C): From ±40ppm Total Frequency Tolerance** Commercial (0° ~ +70°C): From ±15ppm Industrial(-40° ~ +85°C): From ±20ppm Military (-55° ~ +125°C): From ±50ppm Output Load: 15pF (Higher loads available) Rise and Fall Time: 6ns maximum Duty Cycle: 60/40% Shock Survival: Up to 100,000g, 0.5ms, ½ sine Vibration Survival***: 20g, 10~2000Hz swept sine Maximum Process Temperature: 260°C for 20 seconds COMPARISON OF ENABLE/DISABLE OPTIONS When enabled (PIN 1 is high'*) Output Oscillator Current Consumption: When disabled (PIN 1 'low') Output Oscillator Current Consumption: When re-enabled (PIN 1 from low to high) Output recovery * Does not include calibration tolerance. ** Frequency over temperature relative to nominal frequency. *** per MIL-STD-202G Method 204D, Condition D. Random testing is also available PACKAGING OPTIONS Option 'E' Option 'T' Freq. Output Oscillates Normal Freq. Output Oscillates Normal High 'Z' state Stops Very low High 'Z' state Oscillates Lower than normal Delayed Immediate * When Pin 1 is allowed to float it is held 'high' by an internal pull-up resistor. Option 'N' = Pin 1 not connected internally. HGXO oscillators are available either tray packed (<250pcs) or tape and reel (>250 pieces). 16mm tape, 178mm or 330mm reels (EIA 418).
