The supply voltage range spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V rails without an external regulator. This part carries an Active product status. Supplied in Tape & Reel (TR) packaging, the 6-SMD no-lead footprint (3.20 mm x 2.50 mm) is a standard 6-pin oscillator layout, compatible with common pick-and-place and reflow profiles.","metaTitle":"DSC1101CI2-148.5000T MEMS XO 148.5 MHz CMOS ±25 ppm -40°C","metaDescription":"Microchip DSC1101CI2-148.5000T: MEMS-based XO, 148.5 MHz CMOS output, ±25 ppm stability, -40°C to 85°C industrial temp, standby function.

The DSC1101CI2-148.5000T is a MEMS-based oscillator with the same 6-SMD footprint and CMOS output as a standard quartz XO. The MEMS resonator offers better shock/vibration tolerance and faster startup, but the electrical interface (enable/standby pin, supply range, output drive) is designed to be a drop-in replacement for quartz oscillators of the same frequency and package."},{"question":"What is the standby (power down) function of DSC1101CI2-148.5000T?","answer":"The standby (power down) function disables the output and reduces supply current from 35 mA max to 95 µA max. It is controlled by a dedicated pin — pulling it low puts the oscillator into standby; pulling it high or leaving it floating enables normal operation. This is useful for power gating in battery-powered or intermittent-duty systems."},{"question":"Can DSC1101CI2-148.5000T be used in industrial temperature range?","answer":"This makes it suitable for outdoor telecom, factory automation, engine-bay electronics, and similar environments where the ambient temperature can swing below freezing or above 70°C."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1101CI2-148.5000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1101CI2-148.5000T when reusing this data.
