Wide supply range of 2.25V to 3.6V means the oscillator runs from a 2.5V or 3.3V rail without a separate LDO — useful when the clock tree shares the FPGA or ASIC bank voltage. Operating temperature from -20°C to 70°C places it in the commercial band — suitable for indoor telecom, broadcast video, test equipment, and office networking gear where ambient stays within a conditioned environment. Housed in a 20-VFQFN with exposed pad (5.00mm x 3.20mm body, 0.90mm height), the package footprint is compact enough for dense multi-layer boards, but the exposed pad must be soldered to a thermal via array to achieve the rated power dissipation. No direct equivalent or second-source part is listed by Microchip for this exact frequency configuration.","metaTitle":"DSC400-3333Q0099KE1T XO MEMS Oscillator – Microchip","metaDescription":"Active production XO (Standard) MEMS oscillator from Microchip.

The supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within spec. The LVDS output swing and common-mode voltage will track the supply; check the output VOD in the datasheet for AC-coupling decisions."},{"question":"Is the DSC400-3333Q0099KE1T RoHS compliant?","answer":"RoHS compliance is standard for Microchip's DSC400 series.
