Hello,

I have a question about the Cypress clock buffer (CY2308ZXI-1HT).

The Switching Characteristics parameter t5 specifies the output skew between each port of the output terminals CLKA1 to 4 and CLKB1 to 4.

t5 is,
- using internal PLL (S2 = 1, S1 = 1)
- does not use the internal PLL (S2 = 1, S1 = 0) (= Mode that outputs the REF clock signal)
In either case, is the output skew between each port specified by t5?

MPN: CY2308ZXI-1HT

Data sheet "Document Number: 38-07146 Rev. * T"

Hi Morimoto-san,

The t5 parameter which the output to output skew is valid for both modes (when PLL is used and when only REF is used and PLL is bypassed). In either case the output skew between each port specified by t5.

Thanks,

Pradipta
