It integrates a phase-locked loop with bypass mode, so you can either clean up jitter from the incoming clock or pass the reference straight through when the PLL is not needed. The 1:5 fanout ratio is sized for driving multiple loads on a single PCB — think FPGA reference clocks, Ethernet PHY inputs, or multiple ADC sampling clocks — without adding skew. ## 133.33 MHz and the PLL bypass — what they mean for timing closure The maximum output frequency is 133.33 MHz. The PLL with bypass gives two operating modes: with the PLL engaged, output edges align to the input with zero delay; with bypass active, the PLL is shut down and the input clock feeds straight through to the outputs. ## Temperature grade and package — where it fits Rated for 0°C to 70°C ambient, this part is intended for commercial indoor equipment — office networking gear, test equipment, consumer electronics, and telecom line cards in climate-controlled environments. The 8-SOIC package (3.90 mm body width) is a standard surface-mount footprint that reflows easily and is compatible with most PCB assembly lines. The supplier device package is also 8-SOIC, so no footprint mismatch between the case and the recommended land pattern. ## RoHS non-compliant — plan for it This part is marked RoHS non-compliant, meaning it contains lead (Pb) in the solder finish or die attach. For EU markets or any assembly that must meet RoHS exemption rules, you will need to verify whether your end product qualifies for an exemption (e.g., for high-reliability or server applications). ## How it compares to the CY2305SXI-1HT The closest functional peer is the CY2305SXI-1HT. Both are PLL-based zero delay buffers with the same 1:5 fanout, 133.33 MHz maximum frequency, and 3.0 V supply. The key difference is the operating temperature range: the CY23S05SC-1H is rated for 0°C to 70°C (commercial), while the CY2305SXI-1HT covers -40°C to 85°C (industrial).","metaTitle":"Cypress CY23S05SC-1H Zero Delay Buffer, 133.33 MHz, 8-SOIC","metaDescription":"Cypress CY23S05SC-1H PLL-based zero delay buffer, 133.33 MHz max, 1:5 fanout, 3V–3.6V supply, 8-SOIC.
