NOTES:

1. Guaranteed by design and characterization, not 100% tested in production.

2. See http://www.pcisig.com for complete specs

3. Device driven by 932S421BGLF or equivalent

4. Measured as maximum pass band gain. At frequencies w ithin the loop BW, highest point of magnification is called PLL jitter peaking.

5. Measured at 3 db dow n or half pow er point.
