XO95 Series High Reliability SMD Oscillator

XO95 Series High Reliability SMD Oscillator

XO95 oscillators consist of a TTL/CMOS-compatible hybrid circuit with a miniature quartz crystal packaged in a low-profile, ceramic package. Utilising the latest advancements in production technology, the combination of optimised design and high quality materials provide a highly reliable clock oscillator suitable for defence and aerospace applications.

Product features

  • Designed for surface mount applications using infrared, vapor phase, or epoxy mount techniques
  • CMOS and TTL compatible
  • Low power consumption
  • Optional Output Enable/Disable with Tri-State
  • Low EMI emission
  • High shock resistance
  • Full military testing available
  • Hermetically sealed ceramic package

Product applications

  • Military and aerospace: smart munitions, cockpit systems, navigation and engine control systems
  • Industrial, computer and communications: industrial controls, instrumentation and microprocessor clocks
  • Medical: infusion pumps

Absolute maximum ratings

  • Supply voltage Vdd: -0.5V to 7.0V
  • Storage temperature range: -55° to +125°C
  • Maximum process temperature: 260° for 20 seconds

Packaging options

XO95 oscillators are supplied tray packed for quantities greater than 250 pieces. Quantities above 250 pieces are supplied tape and reeled; 16mm tape on 178mm or 330mm reels per EIA 418.

Comparison of enable/disable functions

There are three enable/disable options available, E, T and N. Both the E and T versions have Tri-state outputs. In the E version the oscillator stops, in the T version the oscillator continues to run. The N version (no tristate function) does not have pin 1 connected internally.
