Non-AGTL+ Signal Quality Specifications and Measurement
Guidelines
There are three signal quality parameters defined for non-AGTL+ signals: overshoot/undershoot,
ringback, and settling limit. All three signal quality parameters are shown in Figure 16 for the non-
AGTL+ signal group.

NOTES:
1. V_HI = 1.5 V for all non-AGTL+ signals except for BCLK, PICCLK, and PWRGOOD. V_HI = 2.5 V for BCLK,
PICCLK, and PWRGOOD. BCLK and PICCLK signal quality is detailed in Section 3.1.
