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
MIL testing to MIL-PRF-55310 available
