CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield T552 is a
5x7mm Surface Mount ,
Temperature Compensated Crystal
Oscillator (TCXO). Operating at
3.3Vdc, the T552 will maintained a
±4.6ppm frequency tolerance over
20 years. The T552 is offered for
applications where small size and
high performance are required.
