Notes:
1. Each VDD pin should be filtered with 0.01uf capacitor.
2. Output is enabled if OE pin is floated or not connected.
3. tsu is time to 100PPM stable output frequency after VDD is applied and outputs are enabled.
4. Output Waveform and Connection Diagram define the parameters.
5. Period Jitter includes crosstalk from adjacent output.
6. Contact Sales@Discera.com for alternate output options (LVPECL, LVDS, LVCMOS).
7. Contact Sales@Discera.com for alternative frequency options
8. Jitter limits established by Gen 1.1, Gen 2.1, and Gen 3.0 PCIe standards.
