The PLL has a bypass option, so you can feed the reference straight through without phase locking when you need a simple buffer path. Rated for 133.3 MHz maximum output frequency, it takes a single LVCMOS or LVTTL input and replicates it across eight LVCMOS outputs. The single 3V-to-3.6V supply rail keeps the power plane simple. ## Industrial temperature grade and what it buys you on the line The 133.3 MHz ceiling covers most SPI flash, Ethernet PHY, and FPGA reference clock trees — the 1:8 fanout lets one oscillator drive multiple loads without adding a separate clock fanout IC. The PLL with bypass gives you two modes in one footprint: zero-delay buffering for deskewing a multi-drop clock bus, or simple fanout when the PLL is bypassed. That flexibility saves a board spin if the clock topology changes mid-design.","metaTitle":"Infineon CY2308SXI-1H Fanout Buffer, 133.3 MHz, 16-SOIC","metaDescription":"Infineon CY2308SXI-1H fanout buffer / zero delay buffer, 1:8 ratio, 133.3 MHz max, LVCMOS I/O, -40 to 85°C, 16-SOIC.
