Note:
1. Measured with differential input on CLKIN_2, bypassing the PLL to any output.
2. Skyworks' PCIe Clock Jitter Tool is used to obtain measurements for additive phase jitter. Additive Phase Jitter = sqrt(output jitter
2
- input jitter
2
). Input used is 100 MHz from Si5340.
3. Measurements on 100 MHz output use the template file in the PCIe Clock Jitter Tool.

5. Input clock slew rate of 3.0 V/ns used for jitter measurements.
