Q-Tech Corporation; a supplier of crystal oscillators for space, military, avionics and high-temperature applications; introduces the QTCC353 Series of miniature SMD crystal oscillators designed to provide superior performance over MEMS devices in a wide-range of non-space military, communications, instrumentation and avionics applications. Their unique three-point XO mount and miniature, low-profile (3.2 x 5 x 1.2 mm) packaging provides the industry’s best combination of footprint/headroom, mechanical stability and electrical performance. 

Targeted applications for the QTCC353 Series include:

  • Military – Gun launched munitions and systems and smart munitions, COTS systems
  • Avionics – Navigation, instrumentation
  • Data communications – Ethernet/SynchE, SONET, Fiber Channel
  • Microprocessor Clock – instrumentation, telecom.

The QTCC353 Series is available with HCMOS or LVPECL/LVDS logic outputs and a selection of DC input voltages. Their frequency range is selectable from 25 to 250 MHz with available frequency stability of ±25 ppm from -40°C to 85°C. The devices, housed in a hermetically sealed, ceramic package with gold contacts, are tested for MIL-STD-202 compliance for vibration (Method 204.D) and shock (Method 213.I).

“Our QTCC353 Series has been designed specifically to perform better than MEMS devices in critical non-space applications,” said Scott Sentz, Q-Tech’s director of sales and marketing. “Utilizing three-point mounting and Q-Tech’s proven XO manufacturing technology, these devices provide an exceptional solution in a broad range of applications that require a miniature footprint and high reliability.”
