HGXOHT OSCILLATOR 32.768 kHz High Shock, High Temperature Crystal Oscillator DESCRIPTION For high temperature, high stability and fast start-up applications, Statek offers the AT crystal-based 32.768 kHz HGXOHT oscillator. This oscillator is designed to operate at temperatures up to 200OC. A high-shock version is also offered that features 100,000 g shock survivability. Other features include fast start-up time (0.8 ms typical) and low current operation (500 µA at 25OC.) FEATURES Mechanical shock survivability up to 100,000 g PACKAGE DIMENSIONS High temperature operation up to 200OC G Overall 5 times improvement in total frequency stability when compared to a typical tuning fork design Excellent stability over temperature Fast start-up CMOS output A 2 3 1 4 D F TOP Optional output enable/disable D Low current Hermetically sealed ceramic crystal package B (Double Hermetic Seal) APPLICATIONS Industrial Downhole instrumentation C E TYPICAL MAXIMUM DIM inches mm inches mm A 0.295 7.50 0.302 7.68 Rotary shaft sensors B 0.197 5.00 0.204 5.18 Underground boring tools C* 0.089 2.25 0.098 2.50 D 0.055 1.40 - - E 0.040 1.02 - - SUGGESTED LAND PATTERN F 0.240 6.10 - - G 0.100 2.54 - - *SM1 (Termination material is Au over Ni over W).

The E-version has a TriState 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.
