| EURO QUARTZ Low current consumption, low frequency from 700kHz Low profile, miniature SMD package Full military testing available Testing to MIL-PRF-55310 available DESCRIPTION LSM series oscillators are precision surface mount oscillators with a frequency range from 700kHz to 2.1MHz. The part comprises of a hermetically sealed crystal with a hybrid circuit sealed in a ceramic package with a Kovar lid. Full MIL testing is available. SPECIFICATION Frequency Range: Supply Voltage*: Calibration Tolerance** Code A: Code B: Code C: Frequency Stability*** 0 to +70C: 700kHz to 2.1MHz 2.0MHz standard**** 3.3 or 5.0 Volts 10% 0.01% (100ppm) 0.03% 0.1% -0.12% typical -0.017% maximum 5ppm/V maximum 10ppm/year maximum 750g, 0.3ms, 1/2 sine, 3ppm max. 10g rms, 10-2000Hz, 3ppm max. LSM Series Oscillators Low Power - Low Frequency SMD Oscillator OUTLINE & DIMENSIONS Voltage Coefficient: Ageing: Shock: Vibration: Frequency Change vs. 10% Output Load Change: 1ppm maximum Operating Temperature: -10 to +70C Commercial -40 to +85C Industrial -55 to +125C Military Output Voltage (5.0V supply) HIGH: 4.8V minimum, 4.95V typical LOW: 0.2V maximum, 0.05V typical Rise/Fall Times: 12ns typical Symmetry: 40/60% maximum, 45/55% typical Supply Current 5.0V supply: 400 mA max., 300 mA typical 3.3V supply: 300 mA max., 200 mA typical Packaging: Tray pack (standard) 16mm tape, 17.8cm or 33cm reels Start-up Time: 20ms typical Notes: * ** *** **** PART NUMBERING Example: Contact factory for lower supply voltages Tighter tolerances available Does not include calibration tolerance. Positive variations are much smaller. Contact factory for other frequencies 2.0000MHz LSMA050UMA Frequency Series Designation LSM Calibration Tolerance (see table above) Stability* 100 = 100ppm 50 = 50ppm 25 = 25ppm Output Universal (CMOS) Operating Temp. Range C = Commercial I = Industrial M = Military Supply Voltage** Blank = 5.0 Volts A = 3.3 Volts * ** For other stability requirements enter figure required. For other supply voltage enter required voltage.
