HIGH TEMPERATURE OSCILLATORS High Temperature/High Shock DESCRIPTION An increasing number of applications require the use of hightemperature oscillators. For these applications, Statek offers the CXOHT, CXOMHT, and CXOXHT oscillators. These oscillators are designed to operate at temperatures up to 225ºC with high shock survivability. FEATURES CXOHT CXOMHT CXOXHT 320 kHz - 50 MHz 320 kHz - 50 MHz 1 MHz - 50 MHz PIN CONNECTIONS High temperature operation up to 225OC Excellent stability over temperature Fast start-up High shock resistance CMOS and TTL compatible Optional output enable/disable Low EMI emission Hermetically sealed ceramic package 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.
