Logic - Universal Bus Functions

The 74LVTH16835MTD is a high speed Memory-Transceiver product specifically designed to enable protocols and interconnects on high-speed buses operating at speeds up to 1.5 GHz. It provides a solution for Universal Bus Function (UBF) applications such as U.S.B. 3.2, Fiber Channel, U.S.B. 4.0, as well as communications links between diverse buses, such as IEEE 1394 and Ethernet. The 74LVTH16835MTD is a high-performance, low latency, and low power consumption device that is optimized for forwarding data across a wide variety of buses.

Application Field

The 74LVTH16835MTD is designed to support a range of UBF applications, supporting multi-function buses that require flexible port bridging, and packet adaptation. The devices are ideal for bridging legacy and legacy-to-next-generation buses and also in high-speed digital systems designed to support Ethernet and Fibre Channel (FC) protocols, as well as proprietary communications links. In addition, the device is useful in a variety of mobile, embedded, and communications platforms. As opposed to the traditional UBF solutions, the LVTH16835MTD is capable of simultaneously driving and receiving multiple ports on different buses.

The device is suitable for point-to-point connection of multiple ports and multi-protocol bridging in applications such as, but not limited to, embedded and communications systems. In addition, the device is suitable for bridging legacy and legacy-to-next-generation buses, as well as MEMS (microelectromechanical systems) drives, and in applications requiring a compact and cost-effective solution.

Working Principle

The 74LVTH16835MTD operates on a simple principles and consists of a single chip; four independent receiver channels and four independent transmitter channels. The integrated receiver channels perform level translation and direction control, and can support rates of up to 1.5 GHz. The integrated transmitters are capable of transmitting data at up to 1.5 GHz and include adjustable output levels and recoverable edge triggering. Transmitters and receivers can operate in full throughput at the same time.

The device can be configured to support the interface protocol of the design - including three-level addressing with five address ranges supported, along with eight-byte internal data paths can be used to enhance the performance of the device at the same time. The device also offers a tunable parameter - threshold setup/hold - which allows the user to optimize the device for the applications.

The device includes error reporting capabilities for better managing of system stability, quality of service, and power consumption. It can detect errors in the transmitted data and can report the errors to the host via an error output pin. The device also includes a separate DMA controller for transferring data from the host to the device and vice versa.

Conclusion

The 74LVTH16835MTD is a high speed, low latency, low power peripheral with a wide range of applications. It supports multiple protocols such as U.S.B. 3.2, Fiber Channel, U.S.B. 4.0, Ethernet and Fibre Channel, as well as other proprietary communications links. The device is suitable for a variety of embedded, communications and mobile applications, as well as point-to-point connections and multi-protocol bridging. It includes a DMA controller to ensure high data transfer speeds and a configurable error reporting capabilities for efficient system stability, quality of service, and power management.
