Low Power - Low Frequency SMD Oscillator

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.
