It accepts a single-ended clock input and provides four buffered outputs, with a maximum output frequency of 133.3 MHz. The integrated PLL can be bypassed, allowing the device to function as a simple clock buffer when PLL cleanup is not required. Operating from a 3V to 3.6V supply and rated for -40°C to 85°C, it suits industrial control, telecom line cards, and networking equipment where multiple synchronous clock domains must be derived from one reference. ## 133.3 MHz ceiling and PLL bypass — what they mean for your design The 133.3 MHz maximum frequency covers most reference clocks used in Ethernet PHYs, FPGAs, and SoCs. The PLL bypass mode lets you feed a clean external clock straight through without PLL jitter cleanup. ## Supply and temperature range The 3V to 3.6V supply range aligns with standard 3.3V logic rails. The industrial temperature grade (-40°C to 85°C) covers most indoor and outdoor telecom enclosures, but not extended automotive or downhole applications. The 16-TSSOP package (4.40 mm body width) is a common surface-mount footprint; verify the land pattern matches your board's existing clock-buffer layout. ## Lifecycle and sourcing Note that the part is marked RoHS non-compliant, so it is not suitable for lead-free assembly lines unless explicitly exempted.","metaTitle":"Cypress CY2308ZI-1HT Zero Delay Buffer, 133.3MHz, 16-TSSOP","metaDescription":"Cypress CY2308ZI-1HT PLL-based zero delay buffer, 133.3 MHz max, 3V–3.6V supply, -40°C to 85°C, 16-TSSOP.
