FEATURES
VX822HR and VX820HR are audio cards for PCI bus. They are ‘Universal PCI
64-bit/66 MHz’, which means they can be plugged in 32-bit/33 MHz 5 V PCI
slots as well as in 64-bit/66 MHz 3.3 V keyed PCI slots. The cards are also
compatible with PCI-X interfaces.
VX820e and VX822e are audio cards for PCI EXPRESS
TM
(PCIe
®
) bus. They
are in PCI EXPRESS
TM
x1 format and can thus be plugged into any PCIe
®
slot
(x1, x2, x4, x8, x16, x32).
