The KSZ8842-PMQLI is an Ethernet device and is a member of the KSZ8842 family. This family has an array of high performance, low cost, low power Ethernet integrated circuit devices with advanced functionality. KSZ8842-PMQLI devices combine a Media Access Controller (MAC) and Physical Layer (PHY) within a single integrated device. The KSZ8842-PMQLI is designed for Ethernet system designers and OEMs who want to use a low-cost, low-power solution with simplified design. The device offers features such as: isolated power supplies, high-speed differential transceivers, link auto-negotiation, full-duplex, self-crossover, and adjustable clocking.

The KSZ8842-PMQLI has some distinct advantages compared to other available Ethernet processors. It has a built in two-port PHY, which eliminates the need to buy a separate PHY. The device also saves power due to its power consumption of just 0.7W, which is much lower than most other Ethernet products. The device has extremely low latency, which ensures high data throughput. The device also provides the ability to program the packet length for enhanced packet routing.

The KSZ8842-PMSLI is a great choice for interface controllers. This is because, unlike many other LAN devices, it supports FIFO and round-robin packet scheduling, so that the controller can process incoming data quickly and efficiently. It also supports Tx Packet Bursting, which allows the controller to send data packet bursts to the Ethernet Physical Interface to achieve higher performance. In terms of hardware, the device has a 32-bit Processor/Memory Interface, which allows the controller to communicate with other controllers on the bus.

The KSZ8842-PMQLI also offers a feature called Flow Control. This feature allows the controller to manage the flow of traffic, allowing the flow of information between two connected nodes to be kept balanced. This increases the performance of the network and prevents bandwidth congestion. The device supports Auto-Negotiation, which helps to ensure that the two nodes connected to the device establish a link at the optimal speed. The KSZ8842-PMQLI also supports link fragmentation and re-assembly, allowing it to equip and be used for Quality of Service applications.

In conclusion, the KSZ8842-PMQLI is well-suited for interface controllers. It offers a range of features that make it suitable for Ethernet systems. The device has low power consumption, low latency, and supports Flow Control, Auto-Negotiation, and link fragmentation and reassembly. This makes it a great choice for using as an interface controller in Ethernet systems.
