Bandwidth Allocation Solution for PCI

Express

PCI Express is a point-to-point technology. The number of

lanes to a root complex represents the bandwidth available

for a given system to the memory. This bandwidth is limited

by the system architecture and is usually optimized for a

given system. If more bandwidth is needed from the

memory, the bus of the memory will have to be changed,

and additional cost incurred. Pericom’s PCI Express signal

switch offers a “Bandwidth allocation solution for PCI

Express” with a minimum latency compared to PCI Express

packet switch, and at a very minimum cost.

Pericom Solution

Pericom’s PI2PCIExxx PCI Express Signal Switches offer a

way to allocate PCI Express bandwidth by allowing the

limited PCI Express lanes from the root complex to be

dynamically assigned to different slots of a system, thus

enabling the allocation of bandwidth at the same time. The

conventional Packet Switch does not always include

bandwidth allocation features.

Applications environment:

The PI2PCIE412-C

The PI2PCIE412-C (4-Differential Channel, 2:1

Mux/DeMux) PCI-Express Signal switch was designed

using the high-speed differential broadband switching

technology that provides industry proven PCI Express

compliant physical layer signal processing. PI2PCIE412-C

allows bandwidth allocation of two complete PCI Express

lanes, each representing differential pairs of Rx and Tx

signals, by keeping the RON and CON at the lowest

possible denominations. The switch operates at the PCI

Express bandwidth standard of 2.5Gbps signal processing

speeds with 27” trace lengths at the PCB motherboard board

level, providing 100mV of margins at the eye opening.

The PI2PCIE412 (4-Differential Channel, 2:1 Mux/DeMux)

PCI-Express Signal switch was designed using the high-

speed differential broadband switching technology that

provides industry proven PCI Express compliant physical

layer signal processing. PI2PCIE412 allows bandwidth

allocation of two complete PCI Express lanes, each

representing differential pairs of Rx and Tx signals, by

keeping the RON and CON at the lowest possible

denominations. The switch operates at the PCI Express

bandwidth standard of 2.5Gbps signal processing speeds

with 16” trace lengths at the PCB motherboard board level,

providing 50mV of margins at the eye opening.

The PI2PCIE212 is a 2-Differential Channel, 2:1

Mux.DeMux) PCI-Express Signal switch with identical

specifications as the PI2PCIE412 as described above.

PI2PCIE212-C allows bandwidth allocation of one complete

PCI Express lane, representing differential pairs of Rx and

Tx signals.
