This paper presents the design and development of a PCI Express X1 to CPCI Express X1 adapter which researchers can utilize to test, debug and develop CPCI/PXI Express X1 interface cards in PCI Express X1, X4, X8, X16 slots. The adapter uses Multi-layer Impedance Controlled PCB to precisely control the single-ended and differential impedance of the core high-speed transceiver differential signals and the clock signal. Signal integrity was analyzed by HyperLynx and online tests were verified successfully. The experimental and simulation results demonstrate that the adapter is completely compatible with the interface specifications and the transferred signal is correct and effective. |
