What this part is and where it fits
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. This makes it a direct fit for clock-tree fanout in PC motherboards, networking gear, base stations, and industrial control boards where multiple ICs need a synchronous, low-skew clock. The 8-SOIC package and 3V to 3.6V supply range keep the BOM simple: no external PLL loop filter components are required.
Key ratings and what they mean for the BOM
The 133.33 MHz maximum frequency sets the ceiling for the clock tree this part can serve.
Lifecycle and sourcing posture
The CY2305SXI-1HT carries an active lifecycle status and is ROHS3 compliant. 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.
