It operates from a 3 V to 3.6 V supply and is rated for 0°C to 70°C commercial environments — think office networking gear, test equipment, or indoor telecom line cards where a clean, low-skew clock tree is needed across multiple loads. The PLL locks the output edges to the input edge with near-zero propagation delay, which is why it's called a zero-delay buffer. That matters when you're distributing a clock to multiple ICs and can't tolerate the cumulative delay of a simple buffer chain. ## 133.33 MHz ceiling — what it means for your bus The maximum frequency is 133.33 MHz. The 1:5 ratio means one input drives five outputs. That's enough for a small clock tree — say, clocking a CPU, two Ethernet PHYs, an FPGA, and a spare — without needing a second buffer stage. If you need more than five outputs, plan on cascading two parts or using a larger fanout device. ## Temperature grade and environment Rated 0°C to 70°C commercial temperature range. That limits it to indoor, climate-controlled equipment — server rooms, lab instruments, office switches. Not rated for outdoor base stations, motor drives, or under-hood electronics. If your build requires -40°C to 85°C, the sibling CY2305SXI-1HT carries that industrial grade in the same footprint. ## Lifecycle and sourcing posture The CY2305SXC-1HT is listed as Active with ROHS3 compliance. No last-time-buy notice, no NRND flag — standard availability through independent distribution.","metaTitle":"Cypress CY2305SXC-1HT Fanout Buffer, PLL, 133.33 MHz, 8-SOIC","metaDescription":"Cypress CY2305SXC-1HT fanout buffer with PLL, 133.33 MHz max, 1:5 ratio, 3.0-3.6V, 8-SOIC, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PLL":"Yes","Type":"Fanout Buffer (Distribution), Zero Delay Buffer","Input":"Clock","Output":"Clock","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Frequency - Max":"133.33MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Divider/Multiplier":"No/No","Number of Circuits":"1","Ratio - Input:Output":"1:5","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"8-SOIC","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.44000","currency":"USD"},{"qty":10,"price":"$3.09400","currency":"USD"},{"qty":25,"price":"$2.92480","currency":"USD"},{"qty":100,"price":"$2.53470","currency":"USD"},{"qty":250,"price":"$2.40476","currency":"USD"},{"qty":500,"price":"$2.15778","currency":"USD"},{"qty":1000,"price":"$1.81982","currency":"USD"},{"qty":2500,"price":"$1.72883","currency":"USD"},{"qty":5000,"price":"$1.66383","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1c1d5e6035d2b988cad8f31146f1d081.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does CY2305SXC-1HT have a RoHS compliant version?","answer":"Yes, CY2305SXC-1HT is ROHS3 compliant."},{"question":"What are the alternative parts to CY2305SXC-1HT?","answer":"The closest same-function sibling is CY2305SXI-1HT, which is pin-compatible and identical except for its industrial temperature range (-40°C to 85°C).
