Output is LVDS — the differential pair delivers clean edges into 100-ohm terminated traces, making this a natural fit for clocking a high-speed ADC, FPGA, or SerDes transceiver where single-ended CMOS would pick up noise. That stability is specified without the temperature-compensation circuitry a quartz TCXO would need — the MEMS resonator's frequency-vs-temperature curve is inherently flatter. The 105°C ceiling puts it in the industrial-plus bracket: outdoor base stations, motor drives with internal air temperatures above 85°C, and engine-bay electronics that see under-hood heat soak. A commercial-grade 0-70°C oscillator would drift outside the ±50 ppm window above 70°C. Supply voltage spans 2.25V to 3.63V — the same part works on a 2.5V or 3.3V rail without a separate LDO.","metaTitle":"DSC1123DL1-100.0000T – 100 MHz LVDS MEMS Oscillator","metaDescription":"Microchip DSC1123DL1-100.0000T: 100 MHz LVDS XO, MEMS resonator, 2.25-3.63V supply, ±50 ppm stability, industrial temp.
