This is the under-hood temperature band — the oscillator keeps the clock tree alive when the ECU sees 105°C on a summer grade. ## Standby power-down for intermittent operation For a telematics unit that sleeps between ignition cycles, the oscillator's own draw sits below the module's sleep budget — no external load switch needed to disconnect the clock. Active draw is 7.4 mA max at 50 MHz — typical for a CMOS-output oscillator at this frequency. The low disable current means the part can stay powered on the rail and just gate the output, saving a few pennies versus a discrete enable FET. ## Compact 4-SMD footprint for space-constrained boards Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. No via-in-pad required; two-layer boards fan out easily.","metaTitle":"DSC1003DL2-050.0000 MEMS Oscillator 50 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1003DL2-050.0000 — 50 MHz XO, CMOS output, ±25 ppm stability, -40°C to 105°C, AEC-Q100 qualified.

MEMS parts typically have better shock and vibration tolerance, faster start-up, and smaller package size for the same frequency stability. The trade-off is that quartz can sometimes achieve tighter stability (±10 ppm or better) without a TCXO architecture — but for ±25 ppm and automotive-grade requirements, MEMS is a proven alternative."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1003DL2-050.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1003DL2-050.0000 when reusing this data.
