High Stability Oscillator For Harsh Environments: HPO Series

Source: MtronPTI

This oscillator features high stability, a 25 MHz to 150 MHz operating frequency, an HCMOS output, and a -55 oC to +125 oC operating temperature range. It’s ideal for harsh environments with high and low temperatures and high vibration and is particularly well suited for avionics manufacturers due to its tight tolerance with temperature and low drift over a long lifetime.

One application for MtronPTI’s HPO series of high stability oscillators is as a jet engine controller clock. The clock drives A/D converters for accurate and reliable data from the engine while in flight.  This information goes to the autopilot, maintenance recorder and pilot to help increase efficiency and safety.

The commercial avionics industry has grown over the last six years and is projected to continue (according to Lucintel) at about 4% CAGR over the next seven years. Demand for capacity is up and older planes are having their cockpits updated. The HPO oscillator series with ±25 ppm lifetime drift over time, temperature, and initial tolerance, about twice as tight as other oscillator manufacturers’ offerings, makes it well suited for the harsh environments typically encountered in avionics.

There are currently four different models available:

  • HPO-310 / 311:  6 pad ceramic leadless  ±50 ppm or ±25 ppm lifetime drift
  • HPO-320 / 321:  4 gull wing leaded ceramic (same drift choices)

HPO Series at a glance:

  • Operating frequency                               25 MHz to 150 MHz
  • Overall twenty year stability                 +25 ppm or ±50 ppm
  • Operating range                                      -55 °C to +125 °C
  • Output                                                       HCMOS
  • Package                                                     5 x 7 mm, 6 pad leadless or 4 gullwing leaded

In addition to avionics, these oscillators are ideal for small cell base stations, portable instruments, and manpack and vehicular SDR (software defined radios). For additional information, click the data sheet and one sheet brochure links above.
