LVDS differential signaling keeps noise immunity high over long PCB traces, and the 2.25V to 3.63V supply range lets it share a 2.5V or 3.3V rail without an extra regulator. The MEMS base resonator is inherently more robust than quartz — no crystal aging drift, faster startup, and better resistance to 50,000 g shock.

A design using a different DSC1123 variant can drop in the 156.2500 without a board spin, provided the supply voltage and output type match."},{"question":"What does the Enable/Disable function do on this oscillator?","answer":"The Enable/Disable pin (pin 1) lets you tri-state the LVDS output. When pulled low, the output goes high-impedance and supply current drops to 22 mA max (from 32 mA max active). This is useful for power sequencing or sharing a clock line in multi-drop applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123AI2-156.2500","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123AI2-156.2500 when reusing this data.
