PLL-based clock distribution in a 16-SOIC footprint
The Cypress CY23S08SC-3 is a PLL-based zero delay buffer that takes a single LVCMOS or LVTTL input and distributes it to eight LVCMOS outputs at up to 140 MHz. The internal PLL aligns the output edges to the input, eliminating propagation delay through the buffer — useful when clock skew across multiple loads needs to stay tight. It runs from a 3V to 3.6V supply and comes in a 16-SOIC package, surface-mount. This is a single-circuit device with a 1:8 fanout ratio, so one input drives eight clock lines without external fanout logic.
140 MHz ceiling and what it means for your clock tree
The 140 MHz maximum frequency is the upper bound for the clock signal this buffer can cleanly pass.
Commercial temp range — indoor use only
Rated for 0°C to 70°C ambient, this part is suited for office equipment, telecom racks in conditioned spaces, or consumer electronics. It is not rated for the -40°C to 85°C industrial range, so skip it for outdoor base stations, engine-bay electronics, or factory-floor gear exposed to temperature swings. The 16-SOIC package is a standard footprint, easy to hand-rework or automated-place.
Active lifecycle — no LTB pressure
This part remains a viable BOM line for both new designs and ongoing production. Note the RoHS non-compliant status — if your assembly line requires RoHS, verify your exemption or look for a lead-free variant.
