3 Feature/Protocol Descriptions
The following sections give an overview of the PCI1520. Figure 3
–
1 shows a simplified block diagram of the PCI1520.
The PCI interface includes all address/data and control signals for PCI protocol. The interrupt interface includes
terminals for parallel PCI, parallel ISA, and serialized PCI and ISA signaling. Miscellaneous system interface
terminals include multifunction terminals: SUSPEND, RI_OUT/PME (power management control signal), and
SPKROUT.

Power Supply Sequencing
The PCI1520 contains 3.3-V I/O buffers with 5-V tolerance requiring an I/O power supply and an LDO-VR power
supply for core logic. The core power supply, which is always 2.5 V, can be supplied through the VR_PORT terminal
(when VR_EN is high) or from the integrated LDO-VR. The LDO-VR needs a 3.3-V power supply via the V
CC
terminals. The clamping voltages (V
CCA
, V
CCB
, and V
CCP
) can be either 3.3 V or 5 V, depending on the interface. The
following power-up and power-down sequences are recommended.
The power-up sequence is:
1.
Assert GRST to the device to disable the outputs during power up. Output drivers must be powered up in
the high-impedance state to prevent high current levels through the clamp diodes to the 5-V clamping rails
(V
CCA
, V
CCB
, and V
CCP
).
Apply 3.3-V power to V
CC
.
Apply the clamp voltage.
