PEX8311RDK is an application field and working principle designed to provide cost-effective, ultra-low latency and optimized power solutions for the consumer and industrial markets. It has been successfully introduced into products across the consumer, industrial, medical, automotive and other fields, making it the “gold standard” for many high-speed applications.

The PEX8311RDK is a fabric dedicated to bridging multiple high-speed peripherals with bidirectional bandwidths over serial channels. The logic used in the PEX8311RDK consists of a centralized, scalable 4-Tap memory (RM) and several peripheral converters occupying their dedicated slave interface (SPI & SMBus address interface) to generate native byte streams in a variety of application specific protocols.

The host processor interacts with the PEX8311RDK via various serial channels, such as the RM interface, SPI, I2C, etc. Depending on the type of connection, the core logic can be split into two independent cores, one operating in the high speed, bulk data processing mode, and the other in the low speed, command and control mode. The low speed core interacts with the host using high-level commands, while the high-speed core handles direct data streaming.

The RM interface is dedicated to interacting with the peripheral resources, and is designed to support throughput speeds up to 8 GT/s (GigaTranzs) for each lane. The RM interface provides a symmetrical data path for data travelling in both directions simultaneously. The RM interface supports flow control, packet framing and arbitration, allowing the implementation of high-performance fabric-like interfaces.

The PEX8311RDK contains two peripheral interface channels. The first channel is the Serial Peripheral Interface (SPI) channel, which can support throughput speeds up to 4.26 GHz (GHz = billion cycles/second). The second is the SMBus address interface (SMBus A), which can support speeds up to 400 kHz. The SPI and SMBus A channels support all popular types of data transfer.

In addition, the PEX8311RDK supports several advanced features, including in-system clock gating, power management and clock domain switching. The power management feature helps to reduce overall power consumption by automatically powering down peripheral resources during idle periods and resuming operation once new data is available. The clock domain switching feature helps to optimize system performance by enabling multiple power domains to switch clock frequencies according to the type of data currently in transmission.

The PEX8311RDK logic is also designed to provide real-time low latency response times. The possible latency entry points are minimized and the data transfer is fast. This allows the PEX8311RDK to provide a smooth, consistent performance for real-time applications such as automotive, industrial, and defense.

Overall, the PEX8311RDK is an efficient and cost-effective solution for bridging multiple high speed peripherals with optimized power consumption. With its advanced features, real-time low latency response times, and scalability, the PEX8311RDK offers the perfect solution for a wide range of applications.
