LSMA050UMTA Datasheet, PDF (1/1 Pages) EUROQUARTZ limited – Low Power - Low Frequency SMD Oscillator
EURO QUARTZ
LSM Series Oscillators
Low Power - Low Frequency SMD Oscillator
Low current consumption, low frequency from 30kHz
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 30kHz to 200kHz. 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.

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.
