EURO QUARTZ XO26 Series Oscillators 7x5mm SMD High G withstanding CMOS Miniature 7.5 x 5.0 x 2.25mm hermetically-sealed package Shock survivability < 100,000 g Frequency Range 460kHz to 50MHz Power Down or Enable/Disable option Testing to MIL-PRF-55310 available DESCRIPTION XO26 Series oscillators are able to survive high shocks up to 100,000g. The design consists of a hermetically sealed high-shock crystal and a CMOS compatible integrated circuit housed in 7 x 5 x 2.25mm surface mount ceramic package. OUTLINE & DIMENSIONS SPECIFICATION Frequency Range: Supply Voltage: Output Logic: Calibration Tolerance: Frequency Stability over Temperature* Commercial (0~70°C): Industrial (-40~+85°C: Military (-55~+125°C): Total Frequency Stability** Commercial: Industrial: Military: Output Load***: Start-up Time: Rise/Fall Time: Shock Survival: Vibration Survival: Packaging: 460kHz to 50.0MHz 1.8, 2.5, 3.3 or 5.0 Volts ±10% CMOS from ±5ppm at 25°C ±10ppm ±20ppm ±30ppm ±15ppm ±25ppm ±35ppm 15pF 10ms maximum 8ns maximum <100,000g peak, 0.5ms, 0.5 sine 20g rms, 10-2000Hz random Tray pack or tape and reel Notes: * Does not include calibration tolerances ** Frequency over temperature raltive to nominal frequency *** TTL loads and higher CMOS loads available - contact sales. Absolute Maximum Ratings Supply Voltage: -0.5 to 7.0Volts Storage Temperature: -55° to +125°C Maximum Process Temperature: 260°C for 10 seconds ENABLE/DISABLE, POWER DOWN, NOT CONNECTED SHOCK WITHSTAND Code A B C D Shock Level 5,000g 10,000g 20,000g 30,000g Option Power Down P Enable/Disable T Not Connected Blank Pad 1* Pad 3 LOW HIGH LOW HIGH NC High Z Frequency output High Z Frequency output Frequency output * Normally HIGH (internal pull-up resistor) ENABLE/DISABLE vs. POWER DOWN P - Power Down: When Pad 1 is LOW the oscillator stops running T - Enable/Disable: When Pad 1 is LOW the internal oscillator continues to run but the output (Pad 3) is in a high impedance (Z) state. Power Down: Enable/Disable: Disabled current consumption low, recovery delayed. Disabled current consumption lower than normal, Recovery immediate.
