Notes:

* This table contains preliminary information, which is subject to change.

1. TNB-SKEW-SAMEEDGE is the maximum skew within a clock-forwarded group between any two signals or between any signal and its

forward clock, as measured at the package, with respect to the same clock edge.

TNB-SKEW-DIFFEDGE is the maximum skew within a clock-forwarded group between any two signals or between any signal and its

forward clock, as measured at the package, with respect to different clock edges.

2. Input SU and HLD times are with respect to the appropriate clock forward group input clock.

3. The synchronous signals include

PROCREADY, CONNECT, and CLKFWDRST.

4. This value is measured with respect to the rising edge of SYSCLKIN.

5. Test load = 25 pF.
