Electrical Characteristics
4. Applicable only when SATA port signaling rate is 1.5 Gb/s: SATA Vdiff, TX (V_OMAX/MIN8) is measured at the SATA
connector on the transmit side closest to the ICH7 (generally, the motherboard connector), where SATA mV diff
p-p = |SATAxTXP – SATAxTXN|.
5. Applicable only when SATA port signaling rate is 3 Gb/s: SATA Vdiff, TX (_VOMAX/MIN8) is measured at the SATA
connector on the transmit side closest to the ICH7 (generally, the motherboard connector), where SATA mV diff
p-p = |SATAxTXP – SATAxTXN|.
