The dual outputs can be independently assigned HCSL or LVPECL, so one device feeds both a PCIe reference clock (HCSL) and a SerDes PLL (LVPECL) on the same board. Housed in a 20-VFQFN with exposed pad (5.00mm x 3.20mm footprint, 0.90mm height). The DSC400 series is the current-generation MEMS oscillator family; no pin-compatible successor has been announced.","metaTitle":"DSC400-0244Q0009KI1T MEMS XO – Dual 100MHz HCSL/LVPECL","metaDescription":"Microchip DSC400-0244Q0009KI1T XO (Standard) with MEMS resonator, dual 100MHz outputs, HCSL/LVPECL, -40°C~85°C, 20-VFQFN.
