5.2 Pin Descriptions

The following list describes the different input/output cell types that appear in the pin function tables:

•

HS DIFF IN = High speed differential input

•

HS DIFF OUT = High speed differential output

•

PCI BUS = PCI bus tri-state bidirectional buffer with 3.3-V or 5.0-V clamp rail.

•

LV CMOS = 3.3-V low voltage CMOS input or output with 3.3-V clamp rail

•

BIAS = Input/output terminals that generate a bias voltage to determine a driver's operating current

•

Feed through = These terminals connect directly to macros within the part and not through an input or output

cell.

•

PWR = Power terminal

•

GND = Ground terminal

PCI Rail. 5.0-V or 3.3-V PCI bus clamp voltage to set maximum

I/O voltage tolerance of the secondary PCI bus signals. Connect

each one of these terminals to the secondary PCI bus I/O clamp

rail through a 1k

Ω resistor.
