Q1: What are the main features of PLX PCI6520-CB13BIG?
A: PLX PCI6520-CB13BIG is a Transparent FastLane PCI-X to PCI-X bridge designed for high performance bus interconnection. It supports 64-bit operation with asynchronous frequencies from 33 MHz to 133 MHz, 5 V signal input tolerance, 5 V to 3.3 V signal conversion, PCI-X and PCI bus types, and a 10 KB buffer. It also supports up to eight bus masters and uses a 27 mm x 27 mm, 380-ball PBGA package.
Q2: What is PLX PCI6520-CB13BIG used for?
A: This device is used to connect and expand PCI-X or PCI bus segments in systems that require high-speed bus bridging and frequency conversion. Typical applications include servers, storage equipment, telecommunications equipment, networking systems, embedded platforms, and other legacy systems that need PCI-X to PCI-X or PCI-X to PCI connectivity.
Q3: Does PLX PCI6520-CB13BIG have any alternative manufacturer and part number?
A: Direct drop-in replacements are very limited because PCI6520-CB13BIG combines a specific PCI-X bridge architecture, bus configuration, package, pinout, and electrical characteristics. PLX PCI6540-CB13BIG is a closely related PCI-X to PCI-X bridge and supports 64-bit, 133 MHz operation in the same 27 mm x 27 mm PBGA package, but it also provides non-transparent bridging and should not be considered a direct replacement without system-level verification. Pericom PI7C21P100B is another PCI-X to PCI-X bridge that may be evaluated for new or replacement designs. Compatibility should be checked carefully for pinout, bus width, clocking, bridge mode, voltage levels, package, FIFO requirements, and software configuration.
Q4: Is technical support available for PLX PCI6520-CB13BIG?
A: Yes. Technical support can cover PCI-X and PCI bridge configuration, bus arbitration, clock and frequency conversion, FIFO operation, bus-master configuration, signal voltage conversion, PCB design, and replacement evaluation. Nantian Electronics can also provide product parameters, datasheet information, pin diagram instructions, technical assistance, quotation, and purchasing support for PCI6520-CB13BIG.
