Table 22:PCI Express Jitter Specifications (VDDO = 3.3V+5% or 2.5V+5%, TA = -40°C to +85°C)
Note: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is
mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal
equilibrium has been reached under these conditions.
1. Peak-to-Peak jitter after applying system transfer function for the Common Clock Architecture. Maximum limit for PCI Express Gen 1.
2. RMS jitter after applying the two evaluation bands to the two transfer functions defined in the Common Clock Architecture and reporting the
worst case results for each evaluation band. Maximum limit for PCI Express Generation 2 is 3.1ps RMS for tREFCLK_HF_RMS (High Band)
and 3.0ps RMS for tREFCLK_LF_RMS (Low Band).
3. RMS jitter after applying system transfer function for the common clock architecture. This specification is based on the
PCI_Express_Base_r3.0 10 Nov, 2010 specification, and is subject to change pending the final release version of the specification.
4. This parameter is guaranteed by characterization. Not tested in production.

For best jitter performance, keep the single ended clock input slew rates at more than 1.0 V/ns and the differential clock input slew rates more than 0.3 V/ns.
3
All jitter data in this table is based upon all output formats being differential. When single-ended outputs are used, there is the potential that the output jitter may increase
due to the nature of single-ended outputs. If your configuration implements any single-ended output and any output is required to have jitter less than 3 ps rms, contact
IDT for support to validate your configuration and ensure the best jitter performance. In many configurations, CMOS outputs have little to no effect upon jitter.

DJ for PCI and GbE is < 5 ps pp.
5
Output FOD in Integer mode.
6
All output clocks 100 MHz HCSL format. Jitter is from the PCIE jitter filter combination that produces the highest jitter. Jitter is measured w ith the Intel Clock Jitter Tool,
Ver. 1.6.6.
