It carries AEC-Q100 qualification, meaning it has passed the automotive-grade reliability stress and temperature cycling tests required for deployment in vehicle cabin and chassis domains. The MEMS base resonator gives this oscillator inherent resistance to shock and vibration compared to quartz, and it starts up faster — a practical advantage in automotive ignition cycles or industrial equipment that sees frequent power-on events. ## Supply voltage flexibility and standby power Maximum supply current is 6.3 mA at 20 MHz. A standby (power-down) function drops the supply current to 15 µA max, allowing the oscillator to be gated off during system sleep modes without a separate load switch. ## Temperature range and frequency stability Frequency stability is ±25 ppm across the full temperature range, which is tight enough for CAN, LIN, and most 10/100 Ethernet clocking without external trimming. Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The small footprint and low profile suit space-constrained PCBs in automotive ECUs, telematics modules, and portable instrumentation.","metaTitle":"DSC1001DI2-020.0000 MEMS XO – AEC-Q100, 20 MHz, CMOS, Active","metaDescription":"Microchip DSC1001DI2-020.0000 – 20 MHz MEMS oscillator, AEC-Q100 qualified, CMOS output, ±25 ppm stability, -40°C to 85°C, 4-SMD package.

The DSC1001DI2-020.0000 is a MEMS-based oscillator with the same 4-SMD no-lead footprint and 20 MHz CMOS output as a quartz XO. The key differences are better shock/vibration tolerance, faster startup, and AEC-Q100 qualification. The supply voltage range (1.8 V to 3.3 V) and ±25 ppm stability are directly comparable to standard quartz parts. No board layout change is needed if the original quartz oscillator used the same 2.50 mm x 2.00 mm 4-pad footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DI2-020.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DI2-020.0000 when reusing this data.
