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.","metaTitle":"DSC1222NE1-100M0000T MEMS XO 100 MHz LVPECL","metaDescription":"Active MEMS oscillator, 100 MHz LVPECL output, ±50 ppm stability, 2.5V-3.3V supply, -20°C to +70°C.

Verify the downstream PLL's jitter tolerance and the system's phase-noise budget before substituting directly.
