The ±25 ppm stability over the -40 to 85 °C industrial range keeps the jitter budget within the limits of 1 GbE and PCIe Gen 1/2 reference clocks without an external VCXO. ## Wide supply voltage and MEMS reliability The 2.25 V to 3.6 V supply range lets the oscillator run directly from a 2.5 V or 3.3 V rail — no intermediate LDO needed. ## 20-VFQFN package and board layout Housed in a 20-lead VFQFN with exposed pad (5.00 mm × 3.20 mm body, 0.90 mm height), the package requires a thermal via pattern under the paddle for proper heat transfer.","metaTitle":"DSC400-2222Q0104KI2 MEMS XO – 125/100/200/156.25 MHz LVPECL","metaDescription":"Microchip DSC400-2222Q0104KI2 quad-output LVPECL XO: 125, 100, 200, 156.25 MHz, ±25 ppm, 2.25-3.6V, -40 to 85°C, 20-VFQFN.
