NOTES:
1. PCI Express mVdiff p-p = |PETp[x] – PETn[x]|
2. SATA Vdiff, tx (V_IMAX/MIN10 is measured at the SATA connector on the transmit side (generally, the
motherboard connector), where SATA mVdiff p-p = |SATA[x]TXP/RXP – SATA[x]TXN/RXN|
3. VccRTC is the voltage applied to the VccRTC well of the ICH6. When the system is in a G3 state, this is
generally supplied by the coin cell battery, but for S5 and greater, this is generally VccSus3_3.
4. Applies to Ultra DMA Modes greater than Ultra DMA Mode 4
5. This is an AC Characteristic that represents transient values for these signals
6. V_DI = | USBPx[P] – USBPx[N]
7. Applies to High-speed USB 2.0
8. Includes V_DI range
