The MEMS base resonator means no quartz crystal aging curve to track, but the phase-noise floor is higher than a quartz-based VCXO at the same frequency — fine for Ethernet and FPGA reference clocks, less suited to RF synthesis. Supply voltage range is 2.5 V to 3.3 V, so the same BOM line can serve a 2.5 V FPGA bank or a 3.3 V PHY without a separate regulator. Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the small footprint leaves room for decoupling caps close to the supply pin, which is critical for LVDS signal integrity at 125 MHz.","metaTitle":"DSC1203CI3-125M0000T Microchip 125 MHz LVDS MEMS Oscillator","metaDescription":"Active-production 125 MHz LVDS XO, MEMS resonator, ±20 ppm stability, -40 to 85°C, 6-VDFN.
