That ceiling covers most common bus clocks — PCI, Ethernet MAC reference, DDR memory controller interfaces — but not the higher-speed SERDES or RF reference clocks that run above 200 MHz. The integrated PLL has a bypass mode, meaning you can either let the PLL lock and regenerate the output with zero delay relative to the input, or bypass it entirely to pass the input clock through as a simple buffer. This is useful when you need to fan out a clean clock in one part of the board but keep the PLL out of the path for jitter-sensitive sections. ## Supply rail and temperature — where it fits No separate core or I/O voltage needed — one clean 3.3 V plane and a good decoupling cap at each supply pin is the standard layout. ## Package and hand-solderability Housed in a 16-TSSOP with 0.65 mm pin pitch and a 4.4 mm body width. The 1:8 ratio means you get eight copies of the input clock from a single 16-pin package, which saves board space compared to daisy-chaining multiple smaller buffers. Each output is LVCMOS, so it drives standard logic inputs directly without external termination resistors for short traces. Supplied in tube packaging, so it arrives in anti-static tubes suitable for manual assembly or small pick-and-place runs. For reel quantities, check the alternate order code suffix.","metaTitle":"Infineon CY2308ZXC-1H Fanout Buffer, 133.3 MHz, 16-TSSOP","metaDescription":"Active-production zero-delay fanout buffer from Infineon. 1:8 LVCMOS outputs at 133.3 MHz max, 3.0-3.6 V supply, 16-TSSOP.

This is useful when you want zero-delay buffering in one mode and a simple fanout in another, or when the PLL's jitter characteristics aren't needed for a particular clock path."},{"question":"Will CY2308ZXC-1H drop into a board designed for CY2305SXI-1HT?","answer":"Not without a layout change. The CY2308ZXC-1H is a 1:8 buffer in a 16-TSSOP package, while the CY2305SXI-1HT is a 1:5 buffer in a different package (8-SOIC). The pinouts, output count, and footprint differ — a board spin is required to swap between them. Functionally they share the same PLL architecture and 133.3 MHz ceiling, but the ratio and package are not drop-in compatible."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY2308ZXC-1H","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY2308ZXC-1H when reusing this data.
