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.

ENABLE/DISABLE OPTIONS (E/T/N)
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.
