It accepts a single-ended LVCMOS, LVTTL, or crystal input and produces up to four differential HCSL or LVDS outputs at frequencies up to 250 MHz. The 2:4 input-to-output ratio means two reference inputs can be selected to feed four clock outputs, providing fanout for multiple S-RIO ports or link partners from a single PLL.","metaTitle":"841N254BKILF PLL Clock Synthesizer – Renesas FemtoClock NG","metaDescription":"Renesas 841N254BKILF FemtoClock NG PLL clock synthesizer, 250 MHz max, HCSL/LVDS outputs, industrial temp -40°C to 85°C, 32-VFQFN.","metaKeywords":null},"attributes":{"series":"FemtoClock® NG","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"PLL":"Yes","Input":"LVCMOS, LVTTL, Crystal","Output":"HCSL, LVDS","Series":"FemtoClock® NG","Package":"Tray","Main Purpose":"S-RIO 1.3, 2.0","Mounting Type":"Surface Mount","Package / Case":"32-VFQFN Exposed Pad","Frequency - Max":"250MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2.375V ~ 3.465V","Number of Circuits":"1","Ratio - Input:Output":"2:4","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"32-VFQFPN (5x5)","Differential - Input:Output":"No/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$25.45","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$25.45000","currency":"USD"},{"qty":10,"price":"$23.47200","currency":"USD"},{"qty":25,"price":"$22.41680","currency":"USD"},{"qty":80,"price":"$20.77475","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/07e3f7c7884f2c0e3b36b297e171f69f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional alternative to the 841N254BKILF?","answer":"The 9ZXL0851EKKLF is a PLL clock synthesizer from the same Renesas family, but it targets Intel QPI and PCI Express (PCIe) rather than S-RIO. It offers 1:8 fanout at 400 MHz with differential inputs and outputs, whereas the 841N254BKILF accepts single-ended inputs and provides 2:4 fanout at 250 MHz.
