An increasing number of applications require the use of high-
temperature 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.

Supply Current (Typical)
Statek offers three enable/disable options: E, T, and N.
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.
