PACKAGE CHARACTERISTICS  
TABLE 5.0  
Package  
Hermetically sealed, ceramic package with gold plated J leads.  
Notes  
1) Inclusive of calibration @ 25°C , frequency stability vs. change in temperature, supply and load variations, shock,  
vibration and aging (10 years).  
ORDERING INFORMATION  
2) When oscillator is disabled the true output is in a low state (Vol) and the complementary output is in the high state  
(VoH)  
EML5234 - 25.0MHz  
3) Output must be terminated into 50 ohms to Vcc – 2V or Thevenin equivalent.  
4) Duty Cycle measured at 1.977V
