... In addition, the CY2SSTV857-27 features differential feedback clock outputs and inputs. This allows the CY2SSTV857- used as a zero-delay buffer. When used as a zero-delay buffer in nested clock trees, the CY2SSTV857-27 locks onto the input reference and translates with near-zero delay to low-skew outputs ...

... For these applica- tions the CY2SSTV857-27 offers a differential clock input pair as a PLL reference. The CY2SSTV857-27 then can lock onto the reference and translate with near-zero delay to low-skew outputs. For normal operation, the external feedback input, FBIN, is connected to the feedback output, FBOUT ...
