The -40°C to 85°C industrial temperature range means it can sit on a factory-floor PLC backplane, an outdoor telecom line card, or an automotive cabin ECU without derating. Housed in a 16-pin SOIC (3.90 mm width), it's a standard footprint that routes easily on two-layer boards and fits pick-and-place without special handling. ## RoHS status — plan for it This part is RoHS non-compliant. For standard EU RoHS builds, use the RoHS-compliant variant. ## Sourcing and availability The CY23S08SI-4 is sourced through independent distribution and quoted to order against an RFQ. Submit an RFQ for a firm delivery commitment.","metaTitle":"CY23S08SI-4 Clock Buffer, Zero Delay Buffer, 140 MHz, 1:8","metaDescription":"CY23S08SI-4 PLL-based clock buffer, 140 MHz max, 1:8 fanout, LVCMOS I/O, -40°C to 85°C, SOIC-16.

It contains lead. For RoHS-compliant builds, use the CY23S08SXI-4 variant."},{"question":"What is the difference between CY23S08SI-4 and CY23S08SXI-4?","answer":"The difference is RoHS compliance. The CY23S08SI-4 is RoHS non-compliant (contains lead), while the CY23S08SXI-4 is the RoHS-compliant version. All other specifications — 140 MHz max frequency, 1:8 fanout, 3V–3.6V supply, -40°C to 85°C temperature range, SOIC-16 package — are identical."},{"question":"What is CY23S08SI-4's listed PLL feature?","answer":"The CY23S08SI-4 includes a PLL with bypass capability. The PLL cleans incoming jitter and aligns output edges to the input. Bypass mode feeds the input clock directly to the outputs without phase adjustment, useful for test or low-jitter paths."},{"question":"What is CY23S08SI-4's listed type?","answer":"The CY23S08SI-4 is listed as a Clock Buffer and Zero Delay Buffer.
