The Cypress CY2305SXI-1HT is a single-chip fanout buffer and zero delay buffer built around an integrated PLL. It takes one clock input and distributes it to five outputs with near-zero propagation delay — the PLL aligns the output edges to the input reference.
The 133.33 MHz maximum frequency sets the ceiling for the clock tree this part can serve.
There is no last-time-buy or obsolescence notice on record.
Package and mounting note
The 8-SOIC package with 0.154-inch body width and 3.90 mm pitch is a standard footprint shared by many clock buffers and logic devices. Surface-mount assembly is straightforward for reflow; the tape-and-reel variant suits automated pick-and-place. No special handling beyond normal ESD precautions is required.
