COSPAS-SARSAT beacons are battery operated emergency distress transmitters for locating ships or persons when time is critical for survival.  The new Connor-Winfield series CSBxx Series are Surface Mount, 5x7mm, 3.3V, LVCMOS or Clipped Sinewave Temperature Compensated Crystal Oscillators (TCXO) designed to be emergency beacon frequency references requiring tight ± 0.2 ppm frequency stability and frequency slope control of only ±0.7 ppb/min.

The low power dissipation of 6mW allows it to power-up immediately with an accurate frequency. Class 1 devices operate over –40°C to 55°C and Class 2 devices operate–20°C to 55°C. Standard frequencies are 10.0, 12.688375, 12.688575, 12.688656, 12.68875, 16.367, and 20.0 MHz. To save time during the beacon certification process, temperature test data is available from a special on-line URL for each serialized TCXO.
