The supply voltage range spans 1.8V to 3.3V, so the same oscillator can be powered from a 1.8V core rail or a 3.3V I/O rail without a separate LDO. Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.50 mm pitch and no-lead construction mean the PCB land pattern must match the recommended footprint in the datasheet — the solder paste stencil aperture and reflow profile are critical for reliable solder joints.","metaTitle":"DSC1001CI2-004.3000 MEMS XO – 4.3 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1001CI2-004.3000 MEMS oscillator: 4.3 MHz, CMOS output, ±25 ppm stability, 1.8-3.3V supply, AEC-Q100, -40°C to +85°C.

The CMOS output is compatible with most digital clock inputs. The standby (power-down) function is an extra pin that a quartz oscillator may not offer — verify the pinout on your board before substitution."},{"question":"Is the DSC1001CI2-004.3000 AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 ratings. This means it has passed the automotive-grade qualification tests for temperature, reliability, and ESD. It is suitable for use in automotive ECUs, ADAS modules, and other vehicle-mounted electronics where the ambient temperature stays within -40°C to +85°C."},{"question":"What is the closest pin-compatible alternative in the DSC1001 family?","answer":"The DSC1001 series includes many frequency variants in the same 4-SMD no-lead package. A pin-compatible alternative would be any DSC1001 with the same package code and a different frequency — for example, DSC1001CI2-001.0000 for 1 MHz. Confirm the frequency and stability grade match your application before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI2-004.3000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI2-004.3000 when reusing this data.
