Electrical Characteristics
3. Applicable only when SATA port signaling rate is 3 Gb/s: 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|
4. VccRTC is the voltage applied to the VccRTC well of the ICH7. 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.
5. Applies to Ultra DMA Modes greater than Ultra DMA Mode 4
6. This is an AC Characteristic that represents transient values for these signals
7. V_DI = | USBPx[P] – USBPx[N]
8. Applies to High-speed USB 2.0
9. Includes V_DI range
