HIGH TEMPERATURE OSCILLATOR

Leaded High Temperature/High Shock

LHTAT

320 kHz - 50 MHz

DESCRIPTION

An increasing number of high temperature applications

require the use of leaded (through hole) ceramic packaged

oscillators. For these applications, Statek offers the LHTAT

5x7mm oscillator. These oscillators are designed to operate

at temperatures up to 200ºC with high shock survivability.

FEATURES

PIN CONNECTIONS

High temperature operation up to 200^OC

Excellent stability over temperature

High shock resistance

ENABLE/DISABLE OPTIONS (E/N)

Statek offers two enable/disable options: E and N. The E-

version has a Tri-State output and stops oscillating internally

when the output is put into the high Z state. The N-version

does not have PIN 1 connected internally and so has no

enable/disable capability. The following table describes the

Enable/Disable option E.

1. All frequencies, voltages, temperature ranges and enable/disable options may not be

available. Contact factory.

2. Total Tolerance = Calibration Tolerance + Frequency Stability over temperature.

3. Shock survival applies at -55ºC to +125ºC.

4. Per MIL-STD-202G, Method 204D, Condition D. Random vibration testing available.

Note: All parameters are measured at ambient temperature with a 10 M

Ω, 15 pF load.

5. Expected life at 200ºC is in excess of 1,500 hours.
