CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield models 7222
and 7232 are 2.5V LVCMOS,
Surface Mount, Fixed Frequency
Crystal Oscillators (XO) designed
for use in all applications requiring
precision clocks. These oscillators
feature low stand-by current
(10uA) when output is disabled.
The surface mount package is
designed for high-density mounting
and is optimum for mass
production.
