It accepts LVCMOS or LVTTL inputs and outputs LVCMOS signals across nine outputs from a single input, with a PLL that includes a bypass mode for test or low-jitter pass-through operation. ## 133.33 MHz ceiling and the 1:9 fanout The 133.33 MHz maximum frequency covers most standard clock distribution needs — PCI Express Gen 1 (100 MHz), Gigabit Ethernet (125 MHz), and common FPGA reference clocks. The 1:9 input-to-output ratio means a single buffer can drive nine loads directly, which simplifies clock-tree layout and reduces the need for multiple fanout stages. The PLL with bypass mode lets you run the clock cleanly through the buffer without phase-locking when the application demands a deterministic path or lower additive jitter. ## Supply rail and temperature grade This is not an automotive-grade part — no AEC-Q100 qualification is listed, so it is not rated for under-hood or chassis-domain environments. ## Package and footprint Housed in a 16-TSSOP package (4.40 mm width, 0.173\" pitch), surface-mount only. The 16-pin TSSOP footprint is common and shared across the CY2309 family, so a board laid out for the base variant accepts this -1H suffix without layout changes. The supplier device package is 16-TSSOP. ## Lifecycle and compliance No PCN or LTB dates are published for this part number.","metaTitle":"CY2309ZXI-1H Zero Delay Buffer, 133.33 MHz, 16-TSSOP","metaDescription":"CY2309ZXI-1H fanout buffer with PLL bypass, 1:9 ratio, 133.33 MHz max, 3V-3.6V supply, -40°C to 85°C, 16-TSSOP.
