What this clock buffer does on your board
The Cypress CY2308SXC-1 is a fanout buffer and zero delay buffer that takes a single LVCMOS or LVTTL clock input and distributes it to eight LVCMOS outputs with matched edge timing. The internal PLL locks to the input reference and regenerates the outputs so the propagation delay from input to any output is effectively zero — the rising edge at the load aligns with the rising edge at the source. That matters when you are driving multiple clock loads across a PCB and cannot tolerate the cumulative skew of a simple buffer tree. The part runs from a 3V to 3.6V supply, so it drops straight into a 3.3V clock distribution rail. Maximum output frequency is 133.3 MHz, which covers PCI, Ethernet, USB, and most mid-speed processor and FPGA reference clocks. The PLL includes a bypass mode: pull the bypass pin high and the PLL is disabled, the input passes through a delay-matched path to the outputs — useful for test or low-jitter pass-through when you do not need frequency multiplication.
Lifecycle and sourcing posture
The CY2308SXC-1 carries an Active product status and is ROHS3 compliant. There is no NRND flag, no last-time-buy notice, and no announced EOL on this order code. For a BOM line that needs a zero-delay fanout buffer in a 16-SOIC, this part is a current-production choice with no imminent obsolescence risk. No lead-time number is published here, but the part is in active supply and the channel has visibility on multiple date-code lots.
