Its MEMS base resonator provides inherent immunity to the shock and vibration that can cause quartz crystals to frequency-pull or fail — a practical advantage for deployed systems in industrial or outdoor environments. ## ±10 ppm stability over industrial temperature range The supply voltage range of 2.25V to 3.6V allows the oscillator to run from a common 2.5V or 3.3V rail without an additional LDO, simplifying the power tree. ## Enable/Disable function for power management ## 6-SMD package and board integration Housed in a 3.20 mm x 2.50 mm 6-SMD, No Lead package with a seated height of 0.90 mm, the oscillator fits tight-height-profile boards and shares a footprint common among MEMS oscillators in this frequency range.","metaTitle":"DSC1122CI5-400.0000 400 MHz LVPECL MEMS Oscillator -","metaDescription":"DSC1122CI5-400.0000 XO (Standard) from Microchip Technology: 400 MHz LVPECL output, ±10 ppm stability, -40°C to 85°C, MEMS resonator.
