Crystal Oscillators for Military / Defense Applications

Product catalog summary

Overview: Q-Tech and AXTAL provide a range of crystal oscillators designed for military and defense applications, emphasizing precision, reliability, and performance. These oscillators can be screened to MIL-PRF-55310, Level B standards.

Crystal Oscillators (XOs): These oscillators offer superior performance in a low-profile, ceramic, surface-mount package with gold-plated contact pads. They are available with optional solder-dipped terminations.

Voltage Controlled Crystal Oscillators (VCXOs): VCXOs provide tight stability using a control voltage to adjust frequency. They are available in a low-profile ceramic package with gold-plated contact pads. Key models include QTCV356 and QTCV576, with frequencies ranging from 1 to 156.250MHz and stability of ±30 to ±100ppm.

Product Lines and Specifications:

QTCC Series: Frequencies range from 32.768kHz to 250MHz, with stability from ±12 to ±100ppm and temperature ranges from -55°C to 125°C.
QTCT Series: Frequencies range from 10 to 1500MHz, with stability from ±0.5 to ±2.5ppm and temperature ranges from -40°C to 85°C.
AXIOM Series: Frequencies range from 10 to 160MHz, with stability from ±10 to ±100ppb and temperature ranges from -40°C to 85°C.

Oven Controlled Crystal Oscillators (OCXOs): AXTAL OCXOs offer exceptional stability by maintaining a constant temperature.

Temperature Compensated Crystal Oscillators (TCXOs): These oscillators use temperature sensing for tighter stability, available in low-profile ceramic packages.

Surface Acoustic Wave Oscillators (SAWs): AXTAL SAWs provide high frequency in robust packages suitable for harsh environments.

Microcomputer-Compensated Crystal Oscillators (MCXOs): MCXOs offer comparable stability to OCXOs but in a more compact and power-efficient form.

Key Features: All products are designed to withstand high shock and vibration, with screening available to MIL-PRF-55310 standards. They offer various output types, including CMOS, LVPECL, LVDS, and Sine Wave, with supply voltages ranging from 1.8V to 12V.
