The HCSL outputs are differential and intended for high-speed serial links such as PCIe, while the LVCMOS outputs drive general-purpose logic or clock buffers. The differential output path means the part generates clean differential clocks from a single-ended crystal reference — no external differential input is needed. This simplifies the board layout around the oscillator.
The CY28346ZI-2 is specified for Intel CPU servers. It is a processor-specific clock generator, so verify compatibility with your exact Intel chipset and platform revision against the Cypress application note.
