AC ‘97 Component Specification <strong>Revision</strong> <strong>2.1</strong><br />
2.2 64-pin QFP package<br />
The original 64-pin package assignments do not match updated AC ’97 2.0 recommendations for modem<br />
implementations provided in AC ’97 2.0 Appendix B, and are now entirely vendor specific.<br />
Figure 5 shows the original pinout for the 64-pin package. Figure 6 shows the mechanicals. Table 2 gives the<br />
revised pinlist.<br />
