The 2.25 V to 3.6 V supply range covers both 2.5 V and 3.3 V rails — no extra regulator needed when the board runs mixed supplies. LVDS output levels track the supply, so 3.3 V operation delivers full 350 mV swing into 100 Ω termination. ## Package and PCB layout notes The 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height) requires a thermal via array under the paddle for heat sinking and ground return. The 0.50 mm pitch perimeter pads fan out on a 4-layer board without microvias.","metaTitle":"DSC400-0303Q0092KE2T – Microchip Dual 80 MHz LVDS XO, MEMS","metaDescription":"Active Microchip DSC400 XO with two 80 MHz LVDS outputs, ±25 ppm stability, 2.25–3.6 V supply. 20-VFQFN exposed pad.
