Frequency stability is ±25 ppm across the -20°C to +70°C commercial range — tight enough for most 1G/10G Ethernet and PCIe reference clocks without needing a TCXO. Supply voltage spans 2.25 V to 3.6 V, so it runs from a 2.5 V or 3.3 V rail without an extra LDO. ## Enable/disable and package layout notes The 20-VFQFN with exposed pad (5.00 x 3.20 mm body, 0.90 mm height) needs a thermal via pattern under the pad for heat sinking; the 0.50 mm pitch QFN pads fan out on a standard 4-layer board.","metaTitle":"DSC400-2222Q0104KE2T MEMS XO – Microchip, 4 LVPECL Outputs","metaDescription":"Active Microchip DSC400-2222Q0104KE2T MEMS XO, 20-VFQFN, 125/100/200/156.25 MHz LVPECL outputs, ±25 ppm stability, enable/disable.
