The LVDS differential pair keeps the signal clean over a short PCB trace to the FPGA or SerDes reference input. ## Supply rail and power budget The supply range spans 2.25V to 3.63V, so it runs from a 2.5V or 3.3V rail without an intermediate LDO. 6-SMD, no-lead package, 3.20 mm x 2.50 mm body, 0.90 mm seated height. The MEMS die is inside the package; no external crystal or load capacitors are needed.","metaTitle":"DSC1123CI2-333.3333T MEMS XO, LVDS 333.3333 MHz, Active","metaDescription":"Microchip DSC1123CI2-333.3333T MEMS oscillator, 333.3333 MHz LVDS output, ±25 ppm stability, -40°C to 85°C, 6-SMD.

A different frequency (e.g., 312.5 MHz or 400 MHz) would be a different order code but the same pinout — confirm the exact frequency your PLL or FPGA reference requires before substituting."},{"question":"What is the output type and what does it drive?","answer":"LVDS differential output, 333.3333 MHz. It drives a 100-ohm differential termination at the receiver — typical for FPGA clock inputs, SerDes reference clocks, or high-speed ADC/DAC sample clocks. The Enable/Disable pin lets the output be tri-stated for test or power saving."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123CI2-333.3333T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123CI2-333.3333T when reusing this data.
