That frequency and output type target SERDES reference clocks, FPGA high-speed fabric clocks, and data-converter sampling clocks where a differential signal keeps noise off the clock trace. ## Frequency stability and supply rail For a 10 GbE reference clock, ±50 ppm is the standard window; the oscillator does not consume margin that belongs to the rest of the link. Housed in a 6-VDFN package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits dense PCB layouts.","metaTitle":"DSC1123DI1-333.3300T Microchip 333.33 MHz LVDS MEMS","metaDescription":"Microchip DSC1123DI1-333.3300T — 333.33 MHz LVDS XO, MEMS base, ±50 ppm, -40°C to +85°C, 6-VDFN.
