Note:
(1) Specification of Frequency Accuracy is measured by connecting the standard 25MHz crystal unit for
part number XRCGB25M000F3M00R0 of Murata Manufacturing Co., Ltd. on page 11.
This Output Clock Frequency Accuracy does not include accuracy of crystal unit.
Total output clock frequency accuracy could be up to “Output Clock Frequency Accuracy” +
“Crystal unit accuracy”.
(2) The specifications are values applied the jitter filter function specified PCI Express standard.
(3) ±7σ in 10000 sampling or more
(4) Transition time to settle output into ±0.1% of specified frequency after escaping power down mode.
