For a 125 MHz clock, ±50 ppm translates to a maximum frequency error of ±6.25 kHz — sufficient for most non-PLL timing applications, but verify against your receiver's ppm capture range if the oscillator feeds a clock multiplier. ## Supply range and disable function for power-sensitive designs The supply voltage range of 2.25V to 3.63V covers common 2.5V and 3.3V rails without an external regulator. In a battery-powered design, gating the oscillator can save over half the clock-tree power. ## 6-VDFN package and board integration Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this oscillator fits standard 5.0 x 3.2 mm XO footprints. Surface-mount assembly with a 0.90 mm height keeps it compatible with mezzanine card spacing and low-profile enclosures.","metaTitle":"DSC1222BI1-125M0000 XO 125 MHz LVPECL MEMS Oscillator","metaDescription":"DSC1222BI1-125M0000: Microchip DSC1222 series XO, 125 MHz LVPECL output, ±50 ppm stability, -40°C to +85°C, 6-VDFN.
