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.
