Sunnyvale, Calif. - Tapping into technology acquired from HiNT Corp., PLX Technology is spinning a line of PCI-X-to-PCI-X bridging chips for networking and telecom equipment designs.
The PCI 6520 and PCI 6540 are virtually identical in functionality. The difference, however, comes in the 6540, which supports both transparent and nontransparent bridging, said Steve Moore, senior product marketing manager at PLX Technology.
In some backplane applications, designers want nontransparent operation to protect key system resources. Thus, using the nontransparent mode delivered by the 9540, designers can set up an architecture in which a host CPU card serves as a master controlling access from slave cards in the system, Moore said.
The 6520 and 6540 handle 64-bit, 133-MHz PCI-X bridging while also allowing designers to bridge existing 32-bit, 33-MHz and 64-bit, 66-MHz PCI interfaces.
The chips come in a 27 x 27-mm 380-ball PBGA package. Sampling now, the chips are priced at under $30 in high volume.
