Always look and go for Spread Aware Clock Buffers for signal distribution when you want Spread Spectrum signal to pass as they have larger close loop bandwidth. Normal Clock Buffers will filter the spread spectrum signal. Cypress has such buffers with an “S” in the part number. Examples are CY23S02, CY23S05, CY23S08 and CY23S09 with 2, 5, 8 and 9 outputs respectively.
