The supply voltage range of 2.25 V to 3.6 V covers 2.5 V and 3.3 V rails, and the enable/disable function allows the outputs to be tri-stated for power sequencing or test modes. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the package provides a low-inductance ground path through the centre pad — important for signal integrity at 100 MHz HCSL edge rates.","metaTitle":"DSC400-0401Q0103KE1 MEMS XO – 12.288 MHz & 100 MHz","metaDescription":"Microchip DSC400-0401Q0103KE1 XO (Standard) MEMS oscillator.
