The integrated spread-spectrum modulation reduces peak EMI on the output clock — useful when the board must pass radiated-emissions testing without a metal shield. The 1:2 fanout ratio means one input drives two output traces; the PLL cleans up jitter from the source and re-times the edges. Because the part lacks differential outputs, it targets single-ended CMOS clock trees — not LVDS or LVPECL backplanes. ## Supply rail and temperature — what to budget The supply range is 3.13 V to 3.45 V — a 3.3 V nominal rail with ±4 % tolerance. A standard 3.3 V ±10 % rail (2.97 V to 3.63 V) exceeds the upper limit; use a regulated 3.3 V LDO or a switcher with tight setpoint to stay inside the window. The 8-SOIC package (3.90 mm width) is a common footprint; the SOIC-8 land pattern matches standard IPC-7351 guidelines.","metaTitle":"CY25100SXIF PLL Clock Generator – Infineon, 200 MHz, 8-SOIC","metaDescription":"CY25100SXIF from Infineon: PLL-based fanout buffer and spread-spectrum clock generator, 200 MHz max, 1:2 ratio, 3.13–3.45 V, industrial temp, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"PLL":"Yes","Type":"Fanout Buffer (Distribution), Spread Spectrum Clock Generator","Input":"CMOS, Crystal","Output":"CMOS","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Frequency - Max":"200MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.13V ~ 3.45V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Ratio - Input:Output":"1:2","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-SOIC","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.36","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.36000","currency":"USD"},{"qty":10,"price":"$12.06600","currency":"USD"},{"qty":25,"price":"$11.50480","currency":"USD"},{"qty":100,"price":"$9.98940","currency":"USD"},{"qty":250,"price":"$9.54040","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ad6efe5702334296adf94294fb7ebda9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between CY25100SXIF and CY25100SXI?","answer":"The suffix 'F' on CY25100SXIF indicates ROHS3 compliance (lead-free). The CY25100SXI variant (without 'F') is the non-ROHS version. Electrically the two are identical — same PLL, same 200 MHz limit, same 8-SOIC package. If your BOM requires ROHS3, the 'F' suffix is the correct order code."},{"question":"When sourcing CY25100SXIF, what's the closest functional second-source — CY2305SXI-1HT?","answer":"The CY2305SXI-1HT is a PLL-based fanout buffer from the same Infineon family, but it is not a pin-for-pin drop-in. The CY2305 has a 1:5 fanout ratio (vs 1:2 on the CY25100), a 133.33 MHz max frequency (vs 200 MHz), and a different supply voltage range (3.0 V nominal vs 3.13–3.45 V). It also lacks spread-spectrum modulation.
