The PI7C9X1172BLEX is an interface controller chip designed by Pericom Technology. It is the first integrated single-chip PCI Express to PCI-X bridge device, which is intended to bridge between PCI Express and PCI-X buses. It is designed to offer maximum performance and low power consumption. The bridge device offers a scalable solution that enables multi-tier connections between two buses, providing sufficient performance for desktop, workstation, enterprise, and embedded computing environments.

The device is used to bridge the gap between PCI Express and PCI-X buses. It supports a data transfer rate of up to 5.0 Gbps, and is capable of throughputs up to 250 MBytes/sec.for a single-lane, depending on the type of data and the size of the data packet. The device features a single Root Complex port, four ports for Endpoints, and an Auxiliary port for optional Serial ATA, Video, or other devices.

The PI7C9X1172BLEX is designed to offer a complete, cost-effective, and highly reliable PCIe to PCI-X bridge solution. It is designed to be used in a wide range of applications where fast, reliable, and cost-effective communication between the two buses is required, such as in workstations, network appliances, embedded systems, and routers.

The PI7C9X1172BLEX is designed to support both the newer PCI Express and the older PCI-X standards. It implements an open, scalable PCI Express electrical and logical protocol, as defined by the PCI-SIG (Peripheral Component Interconnect Special Interest Group). The device also supports PCI-X protocol and has an advanced Power Management Unit (PMU) to reduce operating power.

The PI7C9X1172BLEX employs three layers of arbitration, arbitration and forwarding, and credit-based flow control to ensure predictable and highly reliable data transmission. It also supports advanced features such as error checking and correction, hot swapping, and bus reset functionality for improved data integrity.

In conclusion, the PI7C9X1172BLEX is an effective and reliable device for bridging between PCI Express and PCI-X buses. It is designed to be used in a variety of applications where fast and cost-effective communication between these two buses is required. It can support up to 5.0 Gbps transfer rate and 250 MBytes/sec. throughputs, offering optimal performance and excellent reliability.
