Notes:
Operating voltage: VDD = +3.3V ± 0.3V.
Test conditions: VDD = +3.3 VDC for typical values; VDD = +3.6 VDC for maximum values.
Definitions:
PCI Bus Power
On: PCI Bus +5V and +3.3V on (modem normally powered by +3.3V from PCI Bus +3.3V
or regulated down from PCI Bus +5V); PCIRST# not asserted.
Off: PCI Bus +5V and +3.3V off (modem normally powered by +3.3V from Vaux or Vpci); PCIRST# asserted.
PCI Clock (PCICLK)
Running: PCI Bus signal PCICLK running;
Stopped: PCI Bus signal PCICLK stopped (off).
Line connection:
Yes: Off-hook, IA powered.
No: On-hook, IA powered down.
Device States:
D3: Low power state. Suspend state can change the system power state; the resulting power state depends
on the system architecture (OS, BIOS, hardware) and system configuration (i.e., other PCI installed cards).
D0: Full power state.
Device and Bus States: D0, B0:
Any PCI transaction, PCICLK running, VCC present.
D3, B1:
No PCI Bus transactions, PCICLK running, VCC present.
D3, B2, B3: No PCI transactions, PCICLK stopped, VCC may be present.
D3, B3:
No PCI transactions, PCICLK stopped, no VCC.
Refer to the PCI Bus Power Management Interface Specification for additional information.
