Product details

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.

Frequently asked questions

Can CY2305SXI-1HT be used as a zero delay buffer?

Yes, the CY2305SXI-1HT is explicitly a zero delay buffer. Its internal PLL aligns the output clock edges to the input reference, so the propagation delay is effectively zero.

What is the pinout of CY2305SXI-1HT?

The CY2305SXI-1HT comes in an 8-SOIC package. The pinout follows the standard Cypress CY2305 family: one clock input, five clock outputs, VDD, and GND. Refer to the Cypress datasheet for the exact pin assignment.

What is the replacement or equivalent for CY2305SXI-1HT?

No official replacement or pin-compatible equivalent is listed in the Cypress cross-reference for the CY2305SXI-1HT. The part remains active, so a replacement is not needed for current designs.
