LHGAT OSCILLATOR Leaded Military Grade/High Shock 320 kHz - 50 MHz DESCRIPTION An increasing number of military applications require the use of leaded (through hole) ceramic packaged oscillators. For these applications, Statek offers the LHGAT 5x7mm oscillator. This oscillator is designed to operate over a temperature range of -55ºC to 125ºC with high shock survivability. FEATURES Full military testing available Excellent stability over temperature High shock resistance CMOS output / output enable/disable Double hermetically sealed package option Hermetically sealed ceramic package - 5x7mm Through-hole leaded package Reduces mechanical and thermal mounting stresses Robust lead-attach eutectic brazing process Gold Plated Kovar Leads PIN CONNECTIONS 1. 2. 3. 4.

Both the E-version and T-version have Tri-State outputs and differ in whether the oscillator continues to run internally when the output is put into the high Z state: it stops in the E-version and continues to run in the T-version. So, the Eversion offers very low current consumption when the oscillator is disabled and the T-version offers very fast output recovery when the oscillator is re-enabled. The N-version does not have PIN 1 connected internally and so has no enable/disable capability. The following table summarizes the three options. COMPARISON OF ENABLE/DISABLE OPTIONS E AND T T7 E When enabled (PIN 1 is high*) Output Freq. output Freq. output Oscillator Oscillates Oscillates Current consumption Normal Normal Output High Z state High Z state Oscillator Stops Oscillates Current consumption Very low Lower than normal When disabled (PIN 1 is low) 3.

Contact factory. Note: All parameters are measured at ambient temperature with a 10 MΩ, 15 pF load. When re-enabled (PIN 1 changes from low to high) Output recovery Delayed Immediate 7. The T-version is not available for all frequencies. Contact factory. PACKAGING OPTIONS * When PIN 1 is allowed to float, it is held high by an internal pull-up resistor.
