The internal PLL locks to the input reference and regenerates the outputs so the propagation delay from input to any output is effectively zero — the rising edge at the load aligns with the rising edge at the source. That matters when you are driving multiple clock loads across a PCB and cannot tolerate the cumulative skew of a simple buffer tree. The part runs from a 3V to 3.6V supply, so it drops straight into a 3.3V clock distribution rail. Maximum output frequency is 133.3 MHz, which covers PCI, Ethernet, USB, and most mid-speed processor and FPGA reference clocks. The PLL includes a bypass mode: pull the bypass pin high and the PLL is disabled, the input passes through a delay-matched path to the outputs — useful for test or low-jitter pass-through when you do not need frequency multiplication. ## Lifecycle and sourcing posture The CY2308SXC-1 carries an Active product status and is ROHS3 compliant. There is no NRND flag, no last-time-buy notice, and no announced EOL on this order code. For a BOM line that needs a zero-delay fanout buffer in a 16-SOIC, this part is a current-production choice with no imminent obsolescence risk. No lead-time number is published here, but the part is in active supply and the channel has visibility on multiple date-code lots.","metaTitle":"Cypress CY2308SXC-1 Fanout Buffer, 133.3MHz, 1:8, 16-SOIC","metaDescription":"Cypress CY2308SXC-1 fanout buffer / zero delay buffer. 133.3 MHz max, 1:8 ratio, LVCMOS I/O, 3V–3.6V supply, 0°C–70°C.

If your clock tree runs at 2.5V, this is not the right buffer."},{"question":"Is CY2308SXC-1 a direct replacement for CY2308SXC-2?","answer":"The evidence does not provide a datasheet comparison between the -1 and -2 suffix variants. Without the -2 spec table, a direct replacement claim cannot be confirmed. Verify the -2 datasheet against the -1's 133.3 MHz max frequency, 1:8 ratio, and 0°C to 70°C temperature range before substituting."},{"question":"When sourcing CY2308SXC-1, what is the closest functional second-source — CY2305SXI-1HT?","answer":"The CY2305SXI-1HT is a 1:5 fanout buffer in the same Cypress family, with the same 133.33 MHz max frequency and PLL architecture, but it is packaged in Tape & Reel and rated for -40°C to 85°C industrial temperature. It is not a pin-for-pin replacement — the output count differs (5 vs 8) and the package may vary. Use it only if your design can accept fewer outputs and the industrial temperature range is acceptable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY2308SXC-1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY2308SXC-1 when reusing this data.
