This dual-output architecture lets a single oscillator feed two clock domains — for example, a 100 MHz PCIe reference and a 125 MHz Ethernet MAC clock — without a second crystal or PLL. ## Enable/Disable for system power management The Enable/Disable function (pin-controlled) allows the oscillator outputs to be tri-stated, dropping supply current from 60 mA typical to 23 mA max. ## Industrial temp range and MEMS reliability ## Package and board layout — 14-VFQFN exposed pad Packaged in a 14-VFQFN with exposed pad (3.20 mm x 2.50 mm body, 0.90 mm height).","metaTitle":"DSC2044FI2-F0012T MEMS XO – 100/125 MHz HCSL, Active","metaDescription":"Microchip DSC2044FI2-F0012T MEMS XO, dual 100/125 MHz HCSL outputs, ±25 ppm stability, -40°C to 85°C, Enable/Disable.
