Electrical Specifications

NOTES:

Refer to Section 4.2 for signal descriptions.

These signals may be driven simultaneously by multiple agents (Wired-OR).

Table 2-7 outlines the signals which include on-die termination (RTT). Table 2-8 outlines

non AGTL+ signals including open drain signals. Table 2-9 provides signal reference

voltages.

NOTES:

These signals have RTT in the package with a 80 Ω pullup to VTT.

These signals have RTT in the package with a 50 Ω pullup to VTT.
