Maximum supply current is 7.2 mA, and the standby (power-down) function drops draw to 15 µA – useful for battery-backed RTC or sleep-mode circuits where the oscillator must be disabled without removing power. The 4-SMD No Lead package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm. The small footprint suits space-constrained automotive modules like camera ECUs or BMS boards.","metaTitle":"DSC1001DI2-028.3750B MEMS XO – Microchip, AEC-Q100","metaDescription":"Active DSC1001DI2-028.3750B from Microchip: MEMS-based XO, 28.375 MHz, CMOS output, AEC-Q100, -40°C to 85°C, ±25 ppm.

The CMOS output swings rail-to-rail, so at 3.3V the output high level is 3.3V, compatible with 3.3V logic families."},{"question":"Is DSC1001DI2-028.3750B a direct replacement for a quartz oscillator?","answer":"Functionally yes – it is a drop-in XO with CMOS output, same 4-pin SMD footprint. The difference is the MEMS resonator inside, which offers better shock/vibration tolerance and typically faster startup than a quartz-based oscillator. No board spin is needed if the original quartz XO uses the same 2.5 mm × 2.0 mm 4-SMD package and supply voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DI2-028.3750B","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DI2-028.3750B when reusing this data.
