The 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal via pattern under the pad for heat sinking; the LVDS output swing is sensitive to the AC-coupling capacitor placement, so keep the trace short to the connector. ## Active production with MEMS reliability advantage","metaTitle":"DSC400-0303Q0086KI2 XO Standard MEMS Oscillator – Microchip","metaDescription":"DSC400-0303Q0086KI2: XO (Standard) MEMS oscillator, LVDS output, dual freq 148.5/148.35 MHz, ±25 ppm, -40~85°C, 20-VFQFN.
