The standby (power down) function pulls the disable current to 15 µA max, allowing the system to gate the clock during sleep modes without a separate load switch — useful for battery-backed automotive modules that must meet quiescent current budgets. ## Supply voltage flexibility and power budget The 1.8 V to 3.3 V supply range covers the three most common digital rails — the same oscillator part number can serve a 1.8 V MCU core clock, a 3.3 V peripheral bus, or a 2.5 V FPGA reference without a separate voltage regulator or BOM variant. Maximum supply current is 7.2 mA — for a 27 MHz CMOS output driving a typical 15 pF load, this puts the power dissipation at roughly 24 mW at 3.3 V, well within the thermal budget of the 4-VDFN package without airflow. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1001CI1-027.0000T 27 MHz MEMS XO AEC-Q100 CMOS Oscillator","metaDescription":"Microchip DSC1001CI1-027.0000T — 27 MHz MEMS XO, CMOS output, ±50 ppm stability, 1.8-3.3 V supply, AEC-Q100 qualified, standby function.

The MEMS resonator offers better shock and vibration tolerance than quartz — this is a genuine advantage in automotive environments. The AEC-Q100 rating confirms it meets automotive reliability requirements. The 4-VDFN package is a standard footprint; verify pad layout compatibility with your existing quartz oscillator's land pattern."},{"question":"What is the difference between MEMS and quartz oscillators?","answer":"MEMS oscillators use a silicon micro-electromechanical resonator instead of a quartz crystal. The MEMS resonator is inherently more resistant to mechanical shock and vibration, has a wider operating temperature range, and typically offers faster start-up time. The trade-off is that close-in phase noise near the carrier can be higher than a good quartz oscillator — though for a 27 MHz CMOS clock feeding a digital ASIC or MCU, the integrated jitter over the relevant band (12 kHz to 20 MHz) is usually within spec."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI1-027.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI1-027.0000T when reusing this data.
