Output is CMOS, meaning it drives a rail-to-rail square wave into a standard digital input without external termination. The 120 MHz rate suits high-speed logic, Ethernet PHY reference clocks, or FPGA fabric clocks. ## Industrial temperature and low-power standby That sub-microamp sleep current lets a battery-backed design gate the oscillator off between active periods without draining the cell. Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. The exposed pad underneath is the thermal path — ensure the PCB has a matching copper land and at least one via to the ground plane to keep the MEMS die within its operating range. The no-lead package is reworkable with hot air if the pad layout is clean and the board is pre-baked per the MSL rating. Product status is Active per Microchip.","metaTitle":"DSC1033AI1-120.0000T MEMS Oscillator 120 MHz CMOS -","metaDescription":"DSC1033AI1-120.0000T: MEMS XO, 120 MHz, CMOS output, 3.3V, ±50 ppm, -40°C to 85°C.

That means no external load capacitors are needed, start-up is nearly instantaneous, and the part is less sensitive to vibration and shock. The trade-off is that MEMS oscillators typically have slightly wider jitter than a high-end quartz XO, but the ±50 ppm stability here is adequate for most digital interfaces."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033AI1-120.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033AI1-120.0000T when reusing this data.
