The supply voltage range spans 1.8V to 3.3V, so the same oscillator can serve as a common reference for 1.8V and 3.3V logic domains without a level translator. Active current draw is 7.2 mA max at full speed — low enough that thermal rise in the no-lead package is negligible even in a confined ECU enclosure. Sourced through independent distribution, this part is quoted to order against the BOM quantity.","metaTitle":"DSC1001AL5-027.0000 – Microchip MEMS XO, 27 MHz, AEC-Q100","metaDescription":"DSC1001AL5-027.0000: Microchip DSC1001 series MEMS XO, 27 MHz, CMOS output, AEC-Q100, -40°C to +105°C, 4-SMD no-lead.

No stock-holding claim is made; each order is sourced per request."},{"question":"Is DSC1001AL5-027.0000 suitable for automotive applications?","answer":"Yes — it carries an AEC-Q100 rating and operates from -40°C to +105°C, which covers under-hood and engine-bay ambient temperatures. The MEMS resonator also provides better shock and vibration tolerance than quartz, making it suitable for chassis-mounted ECUs."},{"question":"Does DSC1001AL5-027.0000 have a standby power-down feature?","answer":"Yes — the standby (power-down) function reduces supply current to 15 µA max when the enable pin is pulled low. This is useful for battery-backed modules that only need the clock reference during active operation."},{"question":"Can DSC1001AL5-027.0000 replace a standard 27 MHz quartz oscillator?","answer":"It is a direct functional replacement for a 27 MHz quartz oscillator in terms of frequency and CMOS output, but the MEMS resonator and AEC-Q100 qualification make it a higher-reliability choice for automotive and industrial environments. The 4-SMD no-lead package is pin-compatible with many standard 7.0×5.0 mm XO footprints — confirm the pad layout against your existing quartz oscillator before committing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001AL5-027.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001AL5-027.0000 when reusing this data.
