5x7mm Surface Mount

TCXO's for Cospas-Sarsat Beacons

Model CSBxx Series

Description:

The Connor-Winfield's CSBxx Series precision

TCXO's are ideally suited for the next generation

of emergency beacon applications. The CSBxx

Series are Surface Mount, 5x7mm, 3.3V, LVCMOS

or Clipped Sinewave Temperature Compensated

Crystal Oscillators (TCXO) designed for emergency

beacon applications requiring tight frequency

stability and low power. The data is serialized and

available on-line to the customer for future reference

during certification. See page 4 for instructions.
