This oscillator can sit in an avionics LRU, a downhole tool, or a satellite payload where the ambient swings from cold-soak to internal heat rise without losing lock. ## Supply flexibility and output drive The supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without a dedicated LDO. The CMOS output swings rail-to-rail, which keeps the edge rates clean into a microcontroller clock input or an FPGA global clock buffer.","metaTitle":"DSC1121BM1-014.7456T MEMS Oscillator","metaDescription":"DSC1121BM1-014.7456T XO (Standard) from Microchip Technology.
