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.","metaTitle":"Cypress CY2305SXI-1HT Fanout Buffer, Zero Delay Buffer","metaDescription":"Cypress CY2305SXI-1HT fanout buffer / zero delay buffer, 1:5 ratio, 133.33 MHz max, 3V-3.6V, -40°C to 85°C, 8-SOIC.

Its internal PLL aligns the output clock edges to the input reference, so the propagation delay is effectively zero."},{"question":"What is the pinout of CY2305SXI-1HT?","answer":"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."},{"question":"What is the replacement or equivalent for CY2305SXI-1HT?","answer":"No official replacement or pin-compatible equivalent is listed in the Cypress cross-reference for the CY2305SXI-1HT.
