The Connor-Winfield X502 is a
3.3V Crystal Controlled Oscillator
(XO) with LVDS Differential
outputs. The X502 is designed for
use with PLL systems requiring
tight frequency stability vs.
temperature. The use of 4x
multiplication is utilized in this
oscillator design.

TABLE 6.0
SMD product suitable for Convection Reflow soldering. Peak temperature
260°C. Maximum time above 220°C, 60 seconds.
Notes
1.0
Inclusive of calibration @ 25°C, frequency stability vs. temperature, control voltage (Vc) = 1.65 Vdc and aging for ten
years.
