It generates multiple clock frequencies from a single silicon die, whereas a quartz oscillator typically provides one fixed frequency. The pinout and supply voltage (2.25V–3.6V) differ from common 3.3V or 5V quartz oscillators; verify compatibility with the target socket before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-4111Q0112KI2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-4111Q0112KI2T when reusing this data.
