These frequencies are the standard pixel and audio clock rates for 1080p video — a single oscillator supplies both domains, eliminating a second crystal or PLL on the board. ## Supply voltage and board integration The 2.25 V to 3.6 V supply rail spans both 2.5 V and 3.3 V logic — the oscillator runs from whichever rail is already on the board, no extra regulator. The 20-VFQFN exposed pad package measures 5.00 mm x 3.20 mm with a 0.90 mm height; the exposed pad needs a thermal via array under the package to pull heat into the ground plane, especially in still-air enclosures. It is a current-production MEMS oscillator suitable for new designs.","metaTitle":"DSC400-0303Q0086KI1 MEMS LVDS Oscillator 148.5/148.35 MHz -","metaDescription":"Active XO (Standard) from Microchip DSC400 series.
