Hi Allen - Did these discussions include NXP opinion in the loop? I found that 1uF (I tried it initially) was enough to make a big difference in HF noise stability on VB_SYS and to deal with short droops, so 4.7uF doesn't sound completely crazy to me. But it is quite a difference from 22uF recommended by NXP. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFHtU79OjLpvpq7dMoRAjVoAJ9smeOO1EAPjSiMvASfDKgyEDtEyACfRX75 mWhBuf6ZrIgTwJBTLuk1SYM= =JEKP -----END PGP SIGNATURE-----
