What this clock buffer does on your board
The CY23S08SC-4 is a PLL-based zero delay buffer that takes a single LVCMOS or LVTTL input and distributes it to eight LVCMOS outputs with near-zero propagation delay. The internal PLL (with bypass option) cleans up jitter on the incoming clock and aligns the output edges to the input, which is useful when you need to fan out a reference clock across multiple loads without skew. Maximum output frequency is 140 MHz, so it covers common 100 MHz and 125 MHz system clocks used in Ethernet switches, PCIe reference clocks, and baseband processors. The single-circuit design (one PLL core) keeps the power draw predictable — no multiple PLLs to synchronise.
Package and footprint for the pick-and-place line
Housed in a 16-SOIC package (0.154-inch body width, 3.90 mm), the CY23S08SC-4 uses a standard footprint that runs on any leaded-SOIC solder profile. No exposed pad, no thermal vias — just route the supply and ground traces to pins 1 and 8 as usual. The 1.27 mm pitch is pick-and-place friendly; tombstoning risk is low with a balanced pad layout. RoHS non-compliant — if your assembly must meet RoHS, this part requires an exemption or you source a lead-free alternative.
Temperature grade — where it can live
That covers most indoor telecom racks, office networking gear, and consumer electronics. Not rated for -40°C industrial or automotive — if your environment sees freezing temperatures or engine-bay heat, the CY2305SXI-1HT sibling offers -40°C to 85°C with a 1:5 fanout and 133.33 MHz max.
