Operating from 2.25 V to 3.6 V, the oscillator spans 2.5 V and 3.3 V rails common in FPGA and ASIC power trees. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the package requires a thermal pad on the PCB for heat dissipation. ## Frequency stability and enable/disable function With ±50 ppm frequency stability, the part holds tight timing margins for 100 MHz clock trees without external compensation.","metaTitle":"DSC400-0244Q0009KI1 MEMS XO – Dual 100 MHz HCSL/LVPECL","metaDescription":"Microchip DSC400-0244Q0009KI1 XO (Standard) with dual 100 MHz outputs, HCSL/LVPECL, 2.25-3.6V supply, ±50 ppm stability, -40 to +85°C.
