LSM Series Oscillators

QUARTZ

EURO

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.

Supply Voltage**

Blank = 5.0 Volts

A = 3.3 Volts

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.

For other stability requirements enter figure required.

** For other supply voltage enter required voltage.

Power Down:

Disabled current consumption low,

recovery delayed.

Enable/Disable:

Disabled current consumption lower than normal,

Recovery immediate.
