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
