Notes:

1. Post processed evaluation through Intel supplied Matlab* scripts. Defined for a BER of 1E-12. Measured values at a

smaller sample size have to be extrapolated to this BER target.

2.

ζ = 0.54 implies a jitter peaking of 3 dB.

3. PCIe* Gen3 filter characteristics are subject to final ratification by PCISIG. Check the PCI-SIG for the latest

specification.

4. Measured on 100 MHz PCIe output using the template file in the Intel-supplied Clock Jitter Tool V1.6.3.

5. Measured on 100 MHz output using the template file in the Intel-supplied Clock Jitter Tool V1.6.3.

6. Measured on 100 MHz, 133 MHz output using the template file in the Intel-supplied Clock Jitter Tool V1.6.3.

7. These jitter numbers are defined for a BER of 1E-12. Measured numbers at a smaller sample size have to be

extrapolated to this BER target.

8. Gen 4 specifications based on the PCI-Express Base Specification 4.0 rev. 0.5.
