Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator fits into compact PCB layouts typical of automotive modules and portable equipment. Surface-mount assembly with a standard reflow profile; no special pad geometry required beyond the 4-pin footprint. Check the MSL before placing — MEMS oscillators are typically MSL 1, but confirm on the reel label.","metaTitle":"DSC1001DI5-066.4860T MEMS XO, 66.486 MHz, CMOS, AEC-Q100","metaDescription":"Active Microchip Technology DSC1001DI5-066.4860T MEMS oscillator, 66.486 MHz CMOS output, ±10 ppm stability, -40°C to 85°C, AEC-Q100.

It carries an AEC-Q100 rating, which qualifies it for automotive-grade reliability stress and temperature cycling."},{"question":"How does the standby function work on DSC1001DI5-066.4860T?","answer":"The standby (power-down) function disables the output and reduces supply current to 15 µA max. It is controlled by a dedicated pin — pulling it low (or high, depending on the logic) puts the oscillator into standby. This allows system-level power gating without an external switch."},{"question":"Can I replace a quartz oscillator with DSC1001DI5-066.4860T?","answer":"Yes, if the board accepts a 4-SMD no-lead package and 1.8V to 3.3V supply. The MEMS construction provides better shock and vibration tolerance than quartz, and the ±10 ppm stability is comparable to a standard quartz XO. Verify the footprint and supply voltage compatibility first."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DI5-066.4860T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DI5-066.4860T when reusing this data.
