Frequency stability is ±50 ppm, tight enough for a 25 MHz reference driving a 100BASE-TX PHY or a Cortex-M4 PLL without external trimming. ## AEC-Q100 qualification at commercial temperature The AEC-Q100 stamp means the part passed automotive-level stress tests (preconditioning, temperature cycling, HAST, ESD) — relevant for infotainment, telematics, or cabin-domain controllers where the ambient stays above freezing. ## 4-VDFN package and board integration Housed in a 4-VDFN measuring 5.00mm x 3.20mm with a seated height of 0.90mm — the 0.50 mm pitch pads are on the bottom, so the PCB land pattern must match the datasheet footprint for solder joint reliability. ## Active lifecycle — no NRND flags The base product number DSC1001 covers multiple frequencies and stability grades; the full order code DSC1001BC1-025.0000 selects the specific 25 MHz, ±50 ppm variant.","metaTitle":"DSC1001BC1-025.0000 MEMS XO 25 MHz CMOS Oscillator","metaDescription":"Microchip DSC1001BC1-025.0000 MEMS XO, 25 MHz CMOS output, 1.8-3.3V supply, AEC-Q100 qualified, 0-70°C.

The output is CMOS (rail-to-rail swing) and the supply range is 1.8V to 3.3V. At 3.3V supply the output high level exceeds 2.0V, meeting the VIH of any 3.3V CMOS logic family. The same part also works at 1.8V or 2.5V without changing the order code."},{"question":"Does the DSC1001BC1-025.0000 have a direct pin-compatible replacement?","answer":"No pin-compatible second source or alternative is listed in the manufacturer's records. The DSC1001 family is Microchip-only. If you need a second source, the closest functional equivalent would be another 25 MHz MEMS XO in a 4-VDFN 5.0x3.2 mm package (e.g., SiTime or Abracon), but layout and supply voltage must be verified against the datasheet."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001BC1-025.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BC1-025.0000 when reusing this data.
