What this clock buffer does on the board
The W132-10BXT is a PLL-based zero delay buffer from the Spread Aware™ series, designed to regenerate a clock input with deterministic phase alignment and fan it out to multiple loads. It accepts a single-ended clock input and produces up to eleven LVCMOS or LVTTL outputs at frequencies up to 140 MHz, with a 2:11 input-to-output ratio. The zero-delay architecture means the output edges align to the input within the PLL's capture range, making it suitable for synchronising multiple ICs on a single PCB without adding skew.
The maximum frequency is 140 MHz. The PLL locks to the input frequency; divider/multiplier is No/No, so output frequency equals input.
2:11 fanout — eleven clock lines from two reference inputs
The 2:11 ratio means two clock input pins feed eleven output pins. In practice you drive one input and leave the other as a redundant or alternate reference, or use the second input for a different clock domain if the PLL can switch between them. The eleven outputs give you enough fanout for a moderate-sized board with multiple FPGAs, ASICs, or memory banks without adding a second buffer. The outputs are non-differential — single-ended LVCMOS or LVTTL only — so long PCB traces above a few inches need impedance matching and possibly series termination to maintain signal integrity at 140 MHz.

Provenance check — what to look for on the markings
The 24-TSSOP package uses laser-etched date codes and lot numbers. Verify the top-mark font matches the manufacturer's standard for the Spread Aware series.
