Product details

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.

Active lifecycle and sourcing posture

For volume pricing and lead time against a specific BOM quantity, the part is sourced and quoted per RFQ — no stock-holding claim is made here.

Frequently asked questions

What is the maximum frequency of CY23S02SC-1?

The maximum operating frequency is 133 MHz. This ceiling limits the part to reference clocks for PCIe Gen1/Gen2, 1000BASE-T Ethernet, DDR2/3 memory interfaces, and similar sub-133 MHz buses.

Does CY23S02SC-1 support zero delay buffer function?

Yes. The part is explicitly listed as a Zero Delay Buffer, meaning the output clocks are phase-aligned to the input reference within the PLL loop bandwidth. This eliminates propagation delay through the buffer, keeping the clock tree in sync.

What is the closest functional alternative to CY23S02SC-1?

The CY2305SXI-1HT is a functional peer: it also integrates a PLL and zero-delay buffering, runs up to 133 MHz, and adds a 1:5 fanout ratio. The package differs — the CY2305SXI-1HT comes in Tape & Reel, while the CY23S02SC-1 is Bulk.
