The MEMS resonator eliminates the quartz crystal's mechanical failure modes — no start-up reliability issues from shock or vibration, and no frequency drift from crystal aging. The ±50 ppm stability matches or exceeds many quartz XOs in the same frequency and temperature range. The pin-compatible 20-VFQFN footprint drops into existing LVPECL clock sockets without board changes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-2222Q0022KE1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-2222Q0022KE1T when reusing this data.
