TABLE 4.0
The Connor-Winfield TFLD646 is
a Surface Mount Temperature
Compensated Crystal Oscillator
(TCXO). Operating at 3.3Vdc,
the TFLD646 will maintain
±4.6ppm frequency tolerance for
20 years over the Industrial
Temperature Range. The
TFLD646 is offered in a surface
mount package for automated
assembly.
