LVPECL swing provides the edge rate needed to drive differential inputs on high-speed SERDES without additional buffering. ## Power rail flexibility and disable function The enable/disable pin pulls the output to high-Z; max disable current is 22 mA vs 58 mA active, useful for power-gating unused SERDES lanes during sleep. ## MEMS resonator — sourcing and reliability angle MEMS resonators are fabricated on standard CMOS lines — no quartz crystal supply constraints, shorter lead times, and better immunity to shock and vibration than quartz oscillators.","metaTitle":"DSC1122CI5-156.2422T Microchip MEMS Oscillator","metaDescription":"DSC1122CI5-156.2422T: Microchip XO (Standard), 156.2422 MHz, LVPECL output, ±10 ppm stability, -40°C to 85°C, 6-SMD.
