HIGH TEMPERATURE OSCILLATORS
High Temperature/High Shock
DESCRIPTION
CXOHT
300 kHz - 50 MHz
CXOMHT
300 kHz - 50 MHz
CXOXHT
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 200C 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.

1. All frequencies, voltages, temperature ranges and enable/disable options may not be available. Contact factory. 2. Total Tolerance = Calibration Tolerance + Frequency Stability over temperature. 3. For non-high-shock CXOHT and CXOMHT oscillators only. The specification for CXOXHT oscillators is 5,000 g, 0.3 ms, 1/2 sine. 4. Per MIL-STD-202G, Method 204D, Condition D. Random vibration testing available. Note: All parameters are measured at ambient temperature with a 10 M!, 15 pF load.
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.
COMPARISON OF ENABLE/DISABLE OPTIONS E AND T
E
T
When enabled (PIN 1 is high*)
Output Oscillator Current consumption Freq. output Oscillates Normal Freq. output Oscillates Normal
When disabled (PIN 1 is low)
Output Oscillator Current consumption High Z state Stops Very low High Z state Oscillates Lower than normal
When re-enabled (PIN 1 changes from low to high)
Output recovery Delayed Immediate
PACKAGING OPTIONS
* When PIN 1 is allowed to float, it is held high by an internal pull-up resistor.
