The 20-VFQFN with exposed pad (5.00 mm × 3.20 mm body, 0.90 mm height) requires a thermal pad on the PCB for heat sinking; the pad should be connected to ground plane with multiple vias to keep junction temperature within the -40 °C to +85 °C operating range. ## Active production status and sourcing","metaTitle":"DSC400-1111Q0081KI2T MEMS XO – Quad Output LVCMOS","metaDescription":"Active Microchip DSC400 MEMS oscillator, 4 LVCMOS outputs (27/50/25/12 MHz), ±25 ppm stability, -40 to +85°C, 20-VFQFN.
