It integrates a PLL with a bypass option, letting you either clean up jitter through the PLL or pass the input clock straight through for low-latency paths. The part runs from either a 2.5V or 3.3V supply, which simplifies rail selection in mixed-voltage boards. Maximum output frequency reaches 200 MHz (220 MHz on some specs), covering common digital logic, memory interfaces, and FPGA reference clocks. The dual supply voltage support (2.5V and 3.3V) means it can sit on a 2.5V-core FPGA rail or a 3.3V peripheral bus without a level translator. The 1:9 fanout ratio saves board space by replacing multiple lower-density buffers. ## Package and rework considerations The fine pitch means careful alignment during reflow, but the package is not thermally demanding — no exposed pad to solder. Orientation is marked by pin 1 indicator, so verify the footprint before placing. ## Lifecycle and sourcing No end-of-life risk for new designs. The ROHS3 compliance covers EU regulatory requirements.","metaTitle":"CY23EP09ZXI-1H Fanout Buffer, Zero Delay Buffer, 200/220 MHz","metaDescription":"CY23EP09ZXI-1H fanout buffer from Cypress: 1:9 fanout, PLL with bypass, LVCMOS I/O, 2.5V/3.3V supply, -40°C to 85°C, 16-TSSOP.
