Housed in a 20-VFQFN with exposed pad, 5.00 mm × 3.20 mm body and 0.90 mm height — the exposed pad must be soldered to a thermal land on the PCB to meet the datasheet's thermal resistance; the 0.50 mm pitch QFN pads need a solder-paste stencil aperture that matches the land pattern to avoid bridging. Supplied in tape-and-reel (TR), the part is pick-and-place ready for high-volume assembly lines; confirm the MSL level on the reel label before the bake decision. No official second-source or pin-compatible cross is listed by Microchip, but the DSC400 family shares the same 20-VFQFN footprint across frequency variants — a different frequency code can be substituted if the clock tree tolerates the change.","metaTitle":"DSC400-0303Q0086KI2T MEMS XO – 148.5/148.35 MHz LVDS, Active","metaDescription":"Microchip DSC400-0303Q0086KI2T dual-output LVDS oscillator. ±25 ppm stability, -40°C to +85°C, 20-VFQFN.

The supply voltage range is 2.25 V to 3.6 V, so the oscillator operates directly on a 3.3 V rail. The LVDS output is a differential pair and does not use the supply rail for logic-level definition — it meets the LVDS standard regardless of the supply voltage within the operating range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-0303Q0086KI2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-0303Q0086KI2T when reusing this data.
