If you're fighting a failed emissions test on a 32 MHz clock line, this part is the fix without a metal shield. ## Supply rail and temperature envelope Runs from a tight 3.135V to 3.465V rail — that's 3.3V ±5%, so a 3.0V or 3.6V supply is out of spec. ## Package and mounting reality Landed in an 8-SOIC package with 0.154-inch body width and 3.90 mm pitch. Surface-mount, no differential clock outputs — single-ended clock fan-out only. The 1:1 input-to-output ratio means it buffers one clock line, not a fan-out tree. ## Lifecycle and compliance flag The catch: it's RoHS non-compliant, so if your BOM requires lead-free assembly per EU directive, this part won't pass incoming inspection. Confirm your exemption or plan for a separate leaded process.","metaTitle":"CY25811SC Spread Spectrum Clock Generator – Infineon, 8-SOIC","metaDescription":"CY25811SC from Infineon: PLL-based spread spectrum clock generator, 3.3V supply, 8-SOIC.
