The Enable/Disable function lets the system shut down the oscillator output without removing the supply, pulling the disable current down to 22 mA max. ## AEC-Q100 qualification and supply voltage flexibility Rated AEC-Q100, this oscillator is qualified for automotive-grade reliability stress and PPAP — it belongs in an ECU, ADAS sensor module, or infotainment head unit that requires the temperature and durability profile of a production vehicle. ## Package, footprint, and board-level fit Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the footprint is common for 7x5 mm oscillators — layout reuse across the DSC1123 family is straightforward. Surface-mount assembly; the exposed pad is a thermal and mechanical reference, not a signal connection — ensure the pad is soldered to the board ground plane for best thermal transfer.","metaTitle":"DSC1123AI2-125.0000 Microchip MEMS XO, 125 MHz LVDS","metaDescription":"DSC1123AI2-125.0000: Active MEMS oscillator, 125 MHz LVDS output, ±25 ppm stability, AEC-Q100 qualified.

This is the standard under-hood and cabin-grade qualification for ICs used in vehicles."},{"question":"Can DSC1123AI2-125.0000 be used with a 3.3V supply?","answer":"Yes. The specified supply range is 2.25 V to 3.63 V, so a 3.3 V rail is within the operating envelope. No external regulator is needed if the board already has a 3.3 V supply."},{"question":"Is DSC1123AI2-125.0000 a drop-in replacement for standard crystal oscillators?","answer":"It is a direct functional replacement for a 125 MHz LVDS XO in the same 7x5 mm 6-SMD footprint. However, because it uses a MEMS resonator rather than a quartz crystal, the internal timing characteristics differ — confirm that the downstream PLL or clock receiver is compatible with the MEMS oscillator's jitter profile before committing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123AI2-125.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123AI2-125.0000 when reusing this data.
