HIGH TEMPERATURE OSCILLATORS High Temperature/High Shock DESCRIPTION CXOHT CXOMHT CXOXHT 300 kHz - 50 MHz 300 kHz - 50 MHz 1 MHz - 50 MHz 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 200ºC with a total frequency stability of 200 parts-per-million at this temperature. The CXOHT is offered in a 10.16 mm x 4.57 mm package. The CXOMHT oscillator is offered in a 6.50 mm x 5.00 mm package. The CXOXHT oscillator features the smallest size of the three, and is offered in a 3.20 mm x 2.50 mm package.

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 E-version 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.
