The Connor-Winfield TVHB546 is a temperature con-
trolled crystal oscillator (TCXO) with voltage tuning.
Operating at 5Vdc supply, the TVHB546 will maintain
±4.6 ppm frequency tolerance at the nominal control
voltage of 2.5Vdc. By adjusting the control voltage,
the frequency can be tuned a minimum of ±10 ppm
for PLL or electronic tuning applications. The
TVHB546 is offered in a surface mount package for
automated assembly.
