Supply voltage spans 1.8V to 3.3V, so the same part can run off a 1.8V core rail or a 3.3V I/O rail without a separate level translator on the oscillator output. ## Automotive-grade qualification for under-hood and industrial use Product status is Active. ## Standby power-down and low-current operation Normal operation draws 7.2 mA max, which is typical for a 66.6666 MHz CMOS oscillator and leaves headroom for the rest of the clock tree. Housed in a 5.00 mm x 3.20 mm 4-SMD no-lead package, seated height 0.90 mm max.","metaTitle":"DSC1001BL5-066.6666T MEMS Oscillator 66.6666 MHz CMOS","metaDescription":"Microchip DSC1001BL5-066.6666T XO (Standard) MEMS oscillator, 66.6666 MHz CMOS output, ±10 ppm stability, -40°C to 105°C, AEC-Q100.

Normal operation draws 7.2 mA max. The low standby current makes this part a good fit for battery-powered designs that need to conserve energy between active periods."},{"question":"Can DSC1001BL5-066.6666T replace a standard quartz oscillator?","answer":"Yes — it is a drop-in MEMS replacement for a quartz XO in the same 5.00 mm x 3.20 mm 4-SMD package. The CMOS output is compatible with most clock inputs. The ±10 ppm stability matches or exceeds many quartz oscillators, and the MEMS construction is inherently more shock- and vibration-tolerant than a quartz crystal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001BL5-066.6666T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BL5-066.6666T when reusing this data.
