The 7.00 mm x 5.00 mm 6-SMD, No Lead package matches the industry-standard 7x5 mm oscillator footprint, so no layout change is needed when replacing a quartz oscillator of the same size.","metaTitle":"DSC1121AL5-125.0000T MEMS Oscillator – 125 MHz, CMOS","metaDescription":"Microchip DSC1121AL5-125.0000T XO (Standard) – 125 MHz, CMOS output, 2.25V–3.6V supply, -40°C to 105°C, ±10 ppm stability, Enable/Disable.
