DESCRIPTION

320 kHz - 50 MHz

1 MHz - 50 MHz

320 kHz - 50 MHz

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.

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.
