CXOMHT OSCILLATOR 32.768 kHz High Temperature/High Stability/Fast Start-up/High Shock DESCRIPTION For high temperature, high stability and fast start-up applications, Statek offers the AT crystal-based 32.768 kHz CXOMHT oscillator. This oscillator is designed to operate at temperatures up to 200OC with a total frequency stability of 200 parts-per-million, compared to about 1,000 ppm for a tuning fork-based 32.768 kHz oscillator. It is also offered in a high-shock version that features a 10,000 g shock survivability. Other features include fast start-up time (0.8 ms typical) and low current operation (500 µA at 25OC.) actual size side view FEATURES High temperature operation up to 200OC PACKAGE DIMENSIONS Excellent stability over temperature Fast start-up High shock resistance Designed for surface mount applications using infrared, vapor phase, or epoxy mount techniques CMOS and TTL compatible Optional output enable/disable Low EMI emission Hermetically sealed ceramic package Full military testing available TYPICAL APPLICATIONS Industrial MAXIMUM DIM inches mm inches mm A 0.256 6.50 0.263 6.68 Downhole instrumentation B 0.197 5.00 0.204 5.18 Rotary shaft sensors C (SM1) 0.051 1.30 0.055 1.40 Underground boring tools C (SM3/SM5) 0.055 1.40 0.063 1.60 D 0.055 1.40 0.065 1.65 E 0.060 1.52 0.070 1.78 SUGGESTED LAND PATTERN PIN CONNECTIONS 1.

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. The following table describes the Enable/Disable option E.
