It takes a single LVCMOS or LVTTL input and distributes it to nine LVCMOS outputs, with a PLL that can be bypassed for test or low-jitter pass-through. The part runs from a 3V to 3.6V supply and handles clock frequencies up to 133.33 MHz. It is rated for the industrial temperature range of -40°C to 85°C, making it a fit for motor drives, industrial controllers, and outdoor telecom gear where the ambient temperature climbs above commercial limits. ## 133.33 MHz and the 1:9 fanout — what it means for your clock tree The 133.33 MHz ceiling covers most processor, FPGA, and Ethernet PHY reference clocks. The 1:9 ratio means one input drives nine loads. ## Active, ROHS3, industrial temp — no lifecycle surprises This part is listed as Active in production with ROHS3 compliance. The industrial temperature grade (-40°C to 85°C) is the full operating range. ## Sourcing and fit for the BOM The CY2309SXI-1H is sourced through independent distribution and quoted to order against an RFQ. For dual-sourcing resilience, the CY2305SXI-1HT is a functional peer with the same PLL architecture and 133.33 MHz maximum, but a 1:5 fanout ratio — useful when the board needs fewer clock outputs and a smaller package option is preferred.","metaTitle":"Cypress CY2309SXI-1H Fanout Buffer, 133.33 MHz, 16-SOIC","metaDescription":"CY2309SXI-1H fanout buffer from Cypress, 1:9 LVCMOS output, 133.33 MHz max, industrial temp -40°C to 85°C.
