PLX’s PCI6154 = FW/PR21154
- Just drop the PLX part in, no changes needed.
- PLX part offers some performance improvement over Intel (deeper FIFO’s for example)
PLX’s PCI6466 ~ FW/PR21555
- PLX have developed a PCI6456 “Interposer card”
- De-solder Intel device, add Onanon connector and plug interposer in.
- Full parts list/design/Gerber's are available
- Migration guides for both PCI6154 and PCI6466 are available and will be emailed to you today.
Designers should be able to use the PCI 6154 from PLX as a drop-in replacement for any design using the Intel 21154. In addition to being a drop-in replacement, the PCI 6154 has several features to increase performance for your application. The PIC6154 has a larger FIFO size and Flow-thru architecture for higher PCI-to-PCI bridging efficiency. The independent external clock input option provides great flexibility to allow add-in card designs to run the secondary bus frequency independent of the primary bus frequency.
Features
- Application Note available for replacing Intel 21154 with the PLX PCI6154
- Large 1K bytes FIFO for efficient PCI-to-PCI bridging and speed conversion
- PCI 64-bit, 33MHz-66MHz Asynchronous operation
- 3.3V Signaling, 5V-Tolerant
- EEPROM Support for additional register control
The FastLane™ PCI6466 Non-Transparent PCI-to-PCI Bridge from PLX Technology is a dual-mode universal adaptive high performance asynchronous 66MHz 64-bit PCI bridge for servers, storage, DSP, telecommunications, networking and embedded applications. The PCI6466 is offered in a 27x27 mm2 380-ball PBGA. This device is available in leaded and lead-free packaging.
Intel’s 21555 is a PCI peripheral device that performs PCI bridging functions for embedded and intelligent I/O applications. The 21555 has a 64-bit primary interface, a 64-bit secondary interface, and 66MHz capability. The 21555 is a Non-Transparent PCI-to-PCI bridge that acts as a gateway to an intelligent subsystem.
