PCIe 3.0 Protocol Analyzer

PCIe 3.0 technology achieves twice the effective data throughput rate of the PCIe 2.0 standard through a combination of increased data bit rate (5 GT/s moving to 8 GT/s) and the elimination of 8b/10b data encoding, which previously added an overhead of 20 percent to all data transfers. In eliminating 8b10b encoding, PCIe 3.0 technology now relies on the existing data scrambling techniques similar to those used for PCIe 2.0 technology to ensure that receivers maintain lock on the incoming data stream.
