NOTES:
1. The CPUPWRGD, SERR#, PIRQ[H:A], SMBDATA, SMBCLK, LINKALERT#, and SMLINK[1:0] signal has an
open drain driver and SATALED# has an open collector driver, and the V_OH specification does not apply. This
signal must have external pull up resistor.
2. For INIT3_3V only, for low current devices, the following low current specification applies: VOL5 Max is 0.15V
at IOL5 of 2 mA.
3. PCI Express mVdiff p-p = |PETp[x] – PETn[x]|
4. SATA Vdiff, tx (VOMAX/MIN8 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|
5. Maximum I_ol for CPUPWRGD is 12mA for short durations (<500mS per 1.5 s) and 9mA for long durations.
