The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard footprint that matches many 3.2 x 2.5 mm quartz oscillators.

The supply voltage range (2.25 V to 3.63 V) and LVDS output are electrically compatible. The MEMS oscillator has no crystal aging drift and better shock tolerance, but verify the phase noise requirements of your downstream PLL — MEMS oscillators generally have higher phase noise than a good quartz VCXO."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1103CE2-156.2500","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1103CE2-156.2500 when reusing this data.
