Housed in a 20-VFQFN exposed pad package measuring 5.00 mm x 3.20 mm, the part requires a thermal via array under the pad for heat sinking. The 0.90 mm height keeps it compatible with standard 1.6 mm PCB stack-ups. Sourced through independent distribution; quantities confirmed at RFQ.","metaTitle":"DSC400-3333Q0089KI2T MEMS XO LVDS 148.35/148.5 MHz Active","metaDescription":"Microchip DSC400-3333Q0089KI2T: MEMS XO, LVDS output, 148.35/148.5 MHz, ±25 ppm, -40~85°C, 20-VFQFN.
