The integrated PLL includes a bypass mode, letting you feed the reference clock straight through when the phase-alignment loop is not needed. Maximum output frequency is 140 MHz, which sets the ceiling for the clock trees this part can serve — PCI, Ethernet, or general-purpose synchronous logic up to that speed. ## Supply and temperature — fit for indoor digital boards Operates from a 3 V to 3.6 V rail. The 0°C to 70°C commercial temperature grade limits deployment to indoor environments. The single-circuit design serves one clock domain. ## Package and footprint Housed in a 16-pin SOIC with 3.90 mm body width — a standard footprint that routes easily on two-layer boards. Surface-mount assembly keeps the part compatible with reflow processes. The supplier device package is 16-SOIC; no differential I/O on this variant, so it is strictly single-ended clock distribution. ## Lifecycle and sourcing RoHS non-compliant per the original release; if your BOM requires RoHS conformance, verify the revision or plan for a lead-free alternate.","metaTitle":"Cypress CY23S08SC-1H Clock Buffer, Zero Delay Buffer","metaDescription":"Cypress CY23S08SC-1H PLL-based zero delay buffer, 1:8 fanout, 140 MHz max, LVCMOS I/O, 16-SOIC, 0°C to 70°C.
