Description
The Euroquartz EMEM1102 and EMEM1122 series of high performance
oscillators utilize MEMS (Micro Electro-Mechanical System) technology,
offering excellent jitter and stability performance over a wide range of
supply voltages and temperature ranges. The EMEM1102 has a standby
feature allowing it to completely power down when the 'EN' pin is
pulled low; the EMEM1122 outputs are disabled when EN is low.
Both oscillators are available in industry-standard oscillator packages,
including the small 2.5 x 2.0mm and are 'drop-in' replacements for
standard LVPECL quartz crystal oscillators.

Pin 6 VDD should be filtered with 0.1µF capacitor.
tSU is time to 100ppm of output frequency after VDD is applied and outputs are enabled.
Output waveform and test circuit figures below define the parameters.
Output is enabled if pad is floated or not connected.
