Product details

100 MHz LVPECL MEMS oscillator — active production

Supply voltage spans 2.5V to 3.3V, letting a single order code serve both 2.5V and 3.3V logic domains without a separate BOM variant.

LVPECL termination and signal integrity

LVPECL output requires a DC termination — typically a 50-ohm resistor to Vcc-2V — to set the correct common-mode voltage and maintain edge rates at 100 MHz. The 50 mA typical supply current (50mA (Typ)) reflects the differential output stage's bias; when disabled, the part draws 23 mA typical. The 6-VDFN package (0.276" x 0.197", 0.90 mm seated height) is a standard 7.0 x 5.0 mm footprint shared by many MEMS and quartz oscillators — layout reuse is straightforward if migrating from a quartz XO in the same package.

Frequently asked questions

Can the DSC1222NE1-100M0000T replace a quartz oscillator in the same footprint?

The 7.0 x 5.0 mm 6-VDFN package matches the common quartz oscillator footprint, but the MEMS resonator has different startup behavior and jitter characteristics. Verify the downstream PLL's jitter tolerance and the system's phase-noise budget before substituting directly. The Enable/Disable function and supply range are compatible with most quartz XO pinouts.

What is the frequency stability of the DSC1222NE1-100M0000T?

Frequency stability is ±50 ppm over the -20°C to +70°C operating range. This includes the combined effects of temperature, supply voltage, and aging.
