LHGAT OSCILLATOR

Product catalog summary
Overview: The document describes the LHGAT 5x7mm oscillator by Statek, designed for applications requiring leaded ceramic packaged oscillators. It operates over a wide temperature range and offers high shock survivability.
Features: The oscillator provides excellent stability over temperature, high shock resistance, CMOS output with enable/disable options, and a double hermetically sealed package. It is designed to reduce mechanical and thermal mounting stresses and includes gold-plated Kovar leads.
Applications: Suitable for navigation, communications, avionics, flight recorders, engine control, and high mechanical stress environments.
Specifications: The oscillator operates at supply voltages of 1.8 V and 5.0 V, with calibration tolerance starting at ±20 ppm. Frequency stability ranges from ±100 ppm to ±15 ppm depending on the application (military, industrial, commercial). It has a start-up time of 5 ms max and a duty cycle between 40% and 60%.
Dimensions: The package dimensions are provided in both inches and millimeters, with specific measurements for each dimension (A-J).
Pin Connections: The oscillator has four pins: Enable/Disable or No connection, Ground, Output, and VDD.
Enable/Disable Options: Three options are available: E, T, and N. The E-version stops the oscillator when disabled, offering low current consumption. The T-version continues to oscillate, providing fast output recovery. The N-version has no enable/disable capability.
Absolute Maximum Ratings: The supply voltage ranges from -0.5 V to 7.0 V, with a storage temperature range of -55°C to +125°C. The maximum process temperature is 260°C for 20 seconds.
Ordering Information: The document provides a guide on how to order LHGAT oscillators, specifying options for calibration tolerance, temperature range, frequency tolerance, termination, shock level, supply voltage, and enable/disable options.
