The compact land pattern suits dense PCB layouts in optical transceivers or compact radio heads. Because it is a MEMS oscillator, it is not a direct pin-for-pin replacement for a quartz XO unless the output type (LVDS) and supply voltage range match the existing footprint. Confirm the 6-SMD pad layout and the 122.88 MHz frequency before committing the BOM line.","metaTitle":"DSC1103CI2-122.8800T MEMS XO, LVDS, 122.88 MHz, Active","metaDescription":"Microchip DSC1103CI2-122.8800T: MEMS XO, 122.88 MHz LVDS output, ±25 ppm stability, 2.25V–3.63V supply, -40°C to 85°C, active production.

This gives it better shock and vibration immunity and a wider supply voltage range (2.25 V to 3.63 V) while maintaining ±25 ppm stability over -40°C to 85°C."},{"question":"What is the output type of DSC1103CI2-122.8800T?","answer":"LVDS (Low-Voltage Differential Signaling). This is a differential output, so it requires a 100-ohm termination resistor across the pair at the receiver — no pull-up or pull-down resistors. The LVDS swing is typically 350 mV, compatible with most FPGA clock inputs and SERDES reference pins."},{"question":"Is DSC1103CI2-122.8800T compatible with 3.3 V?","answer":"Yes — the supply voltage range is 2.25 V to 3.63 V, so both 3.3 V and 2.5 V rails are within spec. No external regulator is needed when running from a 3.3 V supply."},{"question":"Can I replace a standard 122.88 MHz quartz oscillator with DSC1103CI2-122.8800T?","answer":"Only if the original oscillator is also LVDS output and the package footprint matches the 6-SMD No Lead 3.20 mm x 2.50 mm layout. The MEMS part has a wider supply range and better vibration tolerance, but the output type and pinout must be verified against the existing board."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1103CI2-122.8800T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1103CI2-122.8800T when reusing this data.
