DESCRIPTION
The Connor-Winfield EML5234
is a fixed frequency surface
mount Crystal Controlled
Oscillator (XO) designed for
applications requiring low jitter
and tight frequency stability.
Operating at 3.3V supply
voltage, the EML5234 provides
complementary LVPECL
compatible outputs.
FEATURES
3.3V OPERATION
LVPECL DIFFERENTIAL OUTPUTS
LOW JITTER <1pS RMS
OVERALL FREQUENCY TOLERANCE:
±50ppm
INDUSTRIAL TEMPERATURE RANGE:
0 to 70°C

Package
TABLE 5.0
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).
2) When oscillator is disabled the true output is in a low state (Vol) and the complementary output is in the high state
(VoH)
3) Output must be terminated into 50 ohms to Vcc – 2V or Thevenin equivalent.
4) Duty Cycle measured at 1.977V
