The LVDS differential pair keeps jitter low and common-mode noise rejection high on long traces or through connectors — useful for clocking a SerDes transceiver or an FPGA gigabit transceiver bank. It fits under-hood or cabin domains where the ambient hits -40°C to 85°C and vibration is a given. ## Supply range and disable function Supply voltage spans 2.25V to 3.63V — a single rail covers 2.5V and 3.3V logic families without a separate LDO. 6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. Standard reflow profile for lead-free solder; no special bake unless the moisture-sensitive label says otherwise.","metaTitle":"DSC1123CI2-432.0000T XO 432 MHz LVDS MEMS Oscillator –","metaDescription":"Active-production XO (Standard) from Microchip, 432 MHz LVDS output, AEC-Q100 qualified, -40°C to 85°C, 6-SMD package.

The 100-ohm termination resistor goes across the receiver inputs, not to ground."},{"question":"Is the DSC1123CI2-432.0000T AEC-Q100 qualified?","answer":"Yes, the part carries AEC-Q100 ratings, meaning it passed automotive-grade reliability testing. Suitable for under-hood and cabin electronic modules."},{"question":"How does the DSC1123CI2-432.0000T compare to a standard quartz crystal oscillator?","answer":"It uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically offer faster startup, better shock/vibration tolerance, and smaller package size at the same frequency stability (±25 ppm,). The trade-off is that quartz can achieve tighter initial accuracy and lower phase noise in some designs — but at 432 MHz LVDS, the MEMS approach is the practical choice for automotive and industrial applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123CI2-432.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123CI2-432.0000T when reusing this data.
