The HCSL (High-Speed Current Steering Logic) output is the standard for PCIe reference clocks — this part directly drives a PCIe clock tree without an external level translator. Runs from 2.25 V to 3.6 V, so it works on 3.3 V and 2.5 V rails without a separate regulator — the 3.3 V compatibility question is answered: yes, it operates on 3.3 V with margin. ## Package and PCB layout – 14-VFQFN exposed pad Housed in a 14-VFQFN with exposed pad, 3.20 mm x 2.50 mm body, 0.90 mm height — the thermal pad must be soldered to a ground plane for proper heat dissipation and mechanical stability.","metaTitle":"DSC2044FE1-H0002T MEMS XO – HCSL, 50–200 MHz, Active","metaDescription":"Microchip DSC2044FE1-H0002T MEMS XO, HCSL output, dual frequencies up to 200 MHz, 2.25–3.6V supply, -20°C–70°C, ±50ppm stability, 14-VFQFN.
