The PEX8114-BD13BI G is an interface specializing in digital audio and video switching. Its main application area is to manage the data flow between digital audio and video devices. It helps to ensure that data can be buffered and accurately and quickly transferred without compromising the video and audio quality. It is a single chip solution that can be used for multimedia development.

The PEX8114-BD13BI G chip is a four lane PCI Express (PCIe x4) switch chip, which supports up to four x4 lanes, two x2 lanes, or two x4 lanes, one x4 and one x2 lane. It works on a bidirectional, low-latency connection of 8, 16, or 32 bits, with a max supported bandwidth of 5 GT/s. In addition, it has the capabilities of ASF (Application Specific Formulas) and Crossover Link (CROSSLINK).

PEX8114-BD13BI G supports hot-plugging, allowing any port to be connected or disconnected at any time without interrupting the flow of data. It also has support for Power Management features such as power cycling and auto restart of the device. There is also support for bus mastering and DMA (direct memory access) operations.

In terms of its working principle, the PEX8114-BD13BI G chip is designed to buffer data from one device and send it to another. This is done by using a programmable digital multiplexer (PMux). PMux works by enabling the users to create up to 16 separate logical channels, which can be used for transferring data between devices. This is done by using two data transfer techniques: one is the broadcast mode, which sends data from one device to all connected devices; the other is the unicast mode, which sends data from one device to a specific device. Data is transferred at up to 5GT/s.

The PEX8114-BD13BI G also has several features to ensure data integrity, including CRC (cyclic redundancy check) and ECC (error correction codes). This helps to ensure that data being transferred is free from errors and corruption. Furthermore, the chip has integrated 8Kb of buffer memory, which helps to improve the data transmission performance.

In conclusion, the PEX8114-BD13BI G is a specialized interface chip that is mainly used for digital audio and video switching. It has the capacity to manage data flow between digital devices, and has the capabilities of ASF (Application Specific Formulas) and Crossover Link (CROSSLINK). It also supports hot-plugging and has integrated 8Kb of buffer memory for improved data transmission performance. With the PEX8114-BD13BI G chip, users have the assurance of quality audio and video transmission.
