The integrated PLL (with bypass option) realigns the output edges to the input, making it suitable for synchronizing multiple clock loads in a PCB where trace delays would otherwise accumulate. It operates from a 3V to 3.6V supply and is rated for a maximum output frequency of 133.33 MHz. ## 1:9 fanout — consolidating the clock tree With a 1:9 input-to-output ratio, this single buffer can drive up to nine clock loads from one reference source. That reduces the number of buffer stages needed in a distribution tree, saving board area and BOM line items compared to a 1:5 or 1:4 part where multiple devices would cascade. The outputs are single-ended (no differential pairs), which keeps the routing simple for LVCMOS or LVTTL clock lines on standard PCB layers. ## Commercial temperature grade — indoor use only The operating temperature range of 0°C to 70°C (ambient) limits this part to commercial, indoor, temperature-controlled environments — office equipment, consumer electronics, telecom central-office racks, and similar applications where the ambient stays within that band. It is not rated for industrial motor drives, outdoor telecom cabinets, or automotive under-hood environments where -40°C to +85°C or wider is required. If your design lives in a conditioned space, this grade is cost-effective; if it sees a cold start or hot roof, you need the industrial-temperature variant. ## RoHS non-compliant — plan for exemptions This part is marked RoHS non-compliant, meaning it contains lead (Pb) above the RoHS threshold. For EU-market products or any design governed by RoHS directives, this triggers an exemption claim — typically under exemption 7(c)-I for lead in electronic components. If your BOM requires full RoHS compliance, factor in the paperwork or look at the lead-free alternative suffix. ## 16-TSSOP — footprint and handling The CY23S09ZC-1 comes in a 16-lead TSSOP package (0.173\" body width, 4.40 mm) with a surface-mount footprint. The supplier device package is 16-TSSOP. This is a fine-pitch (0.65 mm typical) package that requires standard SMT assembly — no special process beyond what a typical reflow line handles. The package is rated for the commercial temperature range only.","metaTitle":"Cypress CY23S09ZC-1 Zero Delay Buffer, 133.33 MHz, 16-TSSOP","metaDescription":"Cypress CY23S09ZC-1 PLL-based zero delay buffer clock driver. 1:9 fanout, 133.33 MHz max, 3V-3.6V, 16-TSSOP.

The CY2305SXI-1HT comes in a different package and is RoHS compliant. It is a drop-in replacement only if your design can tolerate the reduced fanout and different package footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY23S09ZC-1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY23S09ZC-1 when reusing this data.
