EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE Low Power - Low Frequency SMD Oscillator 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. Low current consumption, low frequency from 700kHz Low profile, miniature SMD package Full military testing available Testing to MIL-PRF-55310 available LSM Series Oscillators Frequency Range: 700kHz to 2.1MHz 2.0MHz standard**** Supply Voltage*: 3.3 or 5.0 Volts ±10% Calibration Tolerance Code A: ±0.01% (±100ppm) Code B: ±0.03% Code C: ±0.1% Frequency Stability* 0° to +70°C: -0.12% typical -0.017% maximum Voltage Coefficient: ±5ppm/V maximum Ageing: ±10ppm/year maximum Shock: 750g, 0.3ms, ½ sine, ±3ppm max.
