High Frequency
LVPECL Oscillator
Model P752
Description:
The Connor-Winfield P752 is a 5x7 mm,
3.3V LVPECL, Surface Mount, Crystal
Controlled Oscillator (XO) designed for
applications requiring low jitter,
+/-100 ppm, overall frequency tolerance
and -40 to 85 °C operation. The P752 is
designed using a PLL multiplier to achieve
the high frequency output. The RoHS
compliant surface mount package is
optimum for mass production.
