The PowerDrive HT7520 is a high-
speed device that provides two
independent, high-performance
PCI-X bridges, integrated with a
high-speed HyperTransport
technology tunnel. The tunnel
function provides connection
capability to other downstream
HyperTransport technology
devices, allowing greater system
connectivity. As shown in Figure 1,
the front-end HyperTransport
interface (Side A) provides a
configurable 16-bit wide
communication path to the host,
offering up to 6.4GB/s of
bandwidth. Similarly, the back-end
HyperTransport interface (Side B)
provides a configurable 8-bit wide
communication path to a
downstream device, offering up to
3.2GB/s of bandwidth.
o
PCI-X version 1.0a compliant
o
64-bit wide data bus
o
Operational modes of PCI-X and legacy
PCI Local Bus Specification, Revision 2.2
protocol
o
Support for 133-, 100- and 66MHz
transfer rates in PCI-X mode
o
Support for 66- and 33MHz transfer rates
in PCI mode
o
Independent transfer rates and operational
modes for each bridge
o
Support for up to 5 PCI Masters, per
bridge, with clock, request, and grant
signals
o
IOAPIC with up to 12 programmable
interrupts; Legacy Interrupt Controller
and IOAPIC modes supported
o
SHPC-compliant, version 1.1, Hot Plug
