It operates from a 3V to 3.6V supply, making it a direct fit in 3.3V logic clock trees without level translation. Packaged in a 16-SOIC (3.90 mm width), it is a surface-mount device intended for commercial-temperature (0°C to 70°C) environments — think telecom line cards, networking switches, server motherboards, and test equipment where a clean, low-skew clock distribution is needed across multiple loads. ## 1:9 fanout and 133.3 MHz ceiling — what they mean for your clock tree The 1:9 input-to-output ratio means a single input clock can drive up to nine loads (FPGAs, ASICs, PHYs, or other clocked devices) without needing an additional buffer stage. At 133.3 MHz, the device handles common telecom and networking reference frequencies (125 MHz, 100 MHz, 66.66 MHz) with margin. Because the I/O is non-differential (single-ended), trace impedance and termination matter more than with LVDS — keep trace lengths matched and use series termination close to the outputs to maintain signal integrity. The 0°C to 70°C commercial temperature range limits deployment to indoor, controlled environments; it is not rated for industrial or automotive use. ## Active lifecycle — no end-of-life watch for this BOM line Cypress (now part of Infineon) lists the CY2309NZSXC-1H as Active in production. For new builds or a BOM line that needs a stable clock fanout source, this part can be specified without a near-term EOL watch.","metaTitle":"CY2309NZSXC-1H Fanout Buffer, 133.3 MHz, 1:9, 16-SOIC","metaDescription":"Cypress CY2309NZSXC-1H fanout buffer (distribution) IC, 1:9 ratio, 133.3 MHz max, 16-SOIC, 3V-3.6V supply, 0°C to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Fanout Buffer (Distribution)","Input":"Clock","Output":"Clock","Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Frequency - Max":"133.3 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Number of Circuits":"1","Ratio - Input:Output":"1:9","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"16-SOIC","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.73","stockQuantity":0,"priceTiers":[{"qty":26,"price":"$11.60000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e3a4ba6f1a153db2d7742e2660839dd8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY2309NZSXC-1H compatible with 3.3V logic?","answer":"Yes.
