Issue No. 42
PCI 6152 Key Features
PCI Bridging - Up to 66MHz
3.3V signaling, including 5V
input signal tolerance
300mW Power Consumption
15 x 15 mm Tiny BGA Package
32 x 32 mm PQFP Package
Pin Compatible with Intel 21152
Application:
Multi-Head PCI Graphics Card
PLX Product:
PCI 6152 – 32-bit PCI-to-PCI Bridge
Key Benefit:
Allows low voltage ASICs to interface to 5V
PCI systems
Multi-head graphics card ASIC only supports 3.3V
signaling
Multi-head graphics cards allow a single
PC to spread content out over several
monitors. Today’s multi-head graphics
card ASICs use low-voltage fine
geometry technologies such as 0.18 or
0.13 micron CMOS. These processes
don’t usually support 5V signaling. This
logic level incompatibility prevents the
graphics card from directly connecting to the 5V legacy PCI slots which
are commonly found in low cost PCs.
Other Features
Supports delayed transactions
for PCI configuration, I/O and
memory read commands
Hot Swap Friendly
Zero wait state burst
Provides memory write data
buffering in both directions
Provides concurrent primary and
secondary bus operation to
isolate traffic
Provides separate arbitration
support for individual secondary
port
Programmable 2-level arbiter
Enhanced address decoding
32-bit I/O and memory address
decoding
Three-stating of I/O during
power up and power down
A
FastLane
PCI to PCI Bridge solves the problem
The simple addition of the
FastLane
TM
PCI 6152 will quickly solve
this problem. The PCI 6152 from PLX is the leading solution for high
performance 32-bit PCI
multiple head graphics cards.
In the card below, the PCI
6152 provides a universal
logic level signaling allowing
this dual-head graphics card
to operate in both 3.3V and
5V PCI environments.
Graphics engine ASICs
typically support only 3.3V
signaling; adding the PCI
6152 enables the card to work with both 3.3V and 5V logic levels,
creating a broader market for these cards.
