12.3 AC SPECIFICATIONS
June 2009 – Revision 1.5
Pericom Semiconductor
a. Measured with Vtt = 1.2V, HiDrv=’0’,LowDrv=’0’ and Dtx=’0000’.
b. Minimum swing assumes LoDrv = 1, HiDrv = 0 and Dtx =1100
c. Max swing assumes LoDrv = 0, HiDrv = 1, Dtx = 0010, VTT = 1.8V
d. As measured between 20% and 80% points. Will depend on package characteristics.
e. Measured using PCI Express Compliance Pattern
