Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body), the part requires a thermal via array under the pad for proper ground-plane heat sinking; the 0.90 mm height clears typical board-to-board spacing. The part is eligible for new designs and carries no last-time-buy deadline.","metaTitle":"DSC400-3333Q0078KE1 – Microchip 4-output 125 MHz LVDS MEMS","metaDescription":"Active-production MEMS XO, four 125 MHz LVDS outputs, ±50 ppm stability, 2.25–3.6 V supply, 20-VFQFN.
