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…
