133 MHz PLL clock driver with zero-delay buffering
The CY23S02SC-1 is a PLL-based clock driver from Infineon's Spread Aware™ family, combining fanout distribution, frequency multiplication, and zero-delay buffering in a single 8-SOIC package. Its 133 MHz maximum frequency covers common PCIe, Ethernet, and memory reference clock rates — the 1:2 input-to-output ratio lets one clean reference feed two downstream devices without adding a separate fanout buffer. The zero-delay buffer function means the output edges align in phase with the input, critical for clock-tree designs where skew between branches must stay under a few hundred picoseconds. The part accepts LVCMOS or LVTTL inputs and drives LVCMOS outputs, matching the logic levels on most board-level clock trees.
