It integrates a phase-locked loop for frequency synthesis and deskew, and includes both a divider and multiplier path. This part is aimed at clock distribution in digital systems where multiple synchronous loads need a clean, low-skew copy of a reference clock — think telecom line cards, networking gear, server motherboards, and test equipment that run on a 3.3 V rail and stay inside a conditioned environment. ## 110 MHz ceiling and 1:8 fanout — what they mean for the board The 110 MHz maximum frequency sets the upper bound for the clock input you can feed this buffer. If your system runs a 100 MHz reference for a switch ASIC or a 66 MHz PCI bus, this part has headroom. The 1:8 input-to-output ratio means one incoming clock drives eight outputs — enough to feed a handful of FPGAs, PHYs, or processors without adding a second buffer stage. That saves board area and reduces part count on the BOM. ## Supply and temperature — the operating envelope The supply range of 2.97 V to 3.63 V covers a nominal 3.3 V rail with about ±10% tolerance, so it works on a standard 3.3 V power plane. The 0°C to 70°C temperature grade limits this part to commercial/indoor use — no engine bay, no outdoor cabinet in summer, no cold storage. If your application lives in a data centre, office, or lab bench, this is fine. For industrial or automotive environments, you would need the industrial-temperature variant (if one exists in the family). ## Package and field-service angle The CY7B9911V-7JC comes in a 32-lead PLCC with J-leads (32-PLCC, body 11.43 x 13.97 mm). That J-lead footprint is socket-friendly — you can drop this into a PLCC socket on the board, which is a real advantage if you are doing field repairs without a rework station. No hot air, no paste stencil; just pop the old one out and press the new one in. The orientation is obvious from the chamfered corner, so it is hard to get wrong even in a parking lot. ## Lifecycle and compliance This part is listed as Active in production — no last-time-buy notice, no end-of-life pressure. The RoHS compliance status is marked as non-compliant, so if your BOM requires lead-free assembly, you will need to check whether your reflow profile and reliability requirements accept a tin-lead finish or if you need a RoHS-compliant alternative. For legacy designs that already run a tin-lead process, this is not a problem.","metaTitle":"CY7B9911V-7JC RoboClock+™ Clock Buffer, 110 MHz, 1:8","metaDescription":"Cypress RoboClock+™ CY7B9911V-7JC zero delay buffer, PLL-based, 110 MHz max, 1:8 LVTTL fanout, 32-PLCC, 0°C to 70°C.","metaKeywords":null},"attributes":{"series":"RoboClock+™","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"PLL":"Yes","Type":"Clock Buffer, Zero Delay Buffer","Input":"LVTTL","Output":"LVTTL","Series":"RoboClock+™","Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"32-LCC (J-Lead)","Frequency - Max":"110MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2.97V ~ 3.63V","Divider/Multiplier":"Yes/Yes","Number of Circuits":"1","Ratio - Input:Output":"1:8","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"32-PLCC (11.43x13.97)","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$20.33","stockQuantity":0,"priceTiers":[{"qty":15,"price":"$20.33000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c678a73be88bfafe1cf3c30945446a6a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the CY7B9911V-7JC replacement or equivalent?","answer":"There is no direct pin-compatible replacement listed in the official Cypress documentation. The closest functional peer is the CY2305SXI-1HT, which is also a zero delay buffer but in a different package (SOIC-8) with a 1:5 fanout and a wider temperature range (-40°C to 85°C). That part operates at 3.0 V nominal and lacks the divider/multiplier feature. For a drop-in replacement, stick with the CY7B9911V-7JC or check the RoboClock+ family for other density options."},{"question":"Is the CY7B9911V-7JC RoHS compliant?","answer":"No, the CY7B9911V-7JC is marked as RoHS non-compliant. It uses a tin-lead (SnPb) finish. If your assembly process requires lead-free solder, you will need to verify compatibility with your reflow profile or look for a RoHS-compliant variant in the RoboClock+ family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7B9911V-7JC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7B9911V-7JC when reusing this data.
