XO-523
Vishay Dale
Half Size Clock Oscillator Enable/Disable
FEATURES
• Size: 8 pin half size
• Industry standard
• Tri-state enable/disable
• Wide frequency range
• Low cost
• Resistance weld package
• 3.3 V
• Compliant to RoHS Directive 2002/95/EC
The XO-523 series oscillator is half size, has tri-state
enable/disable controlled function, and is with a 3.3 V power
supply voltage. The metal package with pin 4 case ground
acts as shielding to minimize EMI radiation.
• Halogen-free according to IEC 61249-2-21 definition
