The MEMS resonator is inherently more shock- and vibration-tolerant than quartz, which matters in industrial or mobile equipment. Verify the output type: this part drives LVPECL, not LVCMOS — the termination and DC bias differ."},{"question":"How does the enable/disable function work on DSC1122BI2-125.0000T?","answer":"The enable/disable pin (pin 1 on the 6-SMD package) puts the output into a high-impedance state when deasserted, reducing supply current from 58 mA max to 22 mA max. This lets you gate the clock to a downstream device without an external clock buffer."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122BI2-125.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122BI2-125.0000T when reusing this data.
