KSZ8692PBI is a highly integrated 10/100 Ethernet transceiver, media access controller and physical layer transceiver incorporated into a single chip. It is developed for a wide range of embedded applications.

KSZ8692PBI can be used in residential gateways, wireless routers, bridges, Ethernet extenders, and other portable devices. It is also suitable for industrial controls, instrumentation, security and communication devices.

Application Field

The KSZ8692PBI provides an integrated, single-chip solution for 10Base-T/100Base-TX links. It implements the media access controller (MAC) layer, an 8K or 32K-byte packet buffer memory, an integrated CSMA/CD media access controller and physical layer transceiver (PHY).

The integrated MAC layer discovers the most efficient path and performs automatic link monitoring and data packet filtering. The packet buffer memory can store up to 8K or 32K bytes of data and reduce the effects of delayed data. It is able to greatly reduce the data packet processing time, allowing low-cost Ethernet extensions and temporary storage of data.

Additionally, the KSZ8692PBI supports auto-negotiation and auto-polarity functions and can detect wire speed automatically. It also supports multiple packet filtering functions, making it an ideal choice for home networking, small- and medium-sized business networks and embedded applications.

Working Principle

The KSZ8692PBI contains two buffers, an 8K or 32K-byte buffer for receiving data and a 4K-byte buffer for sending data. The device has an integrated 10/100Base-TX transceiver, which implements the media access controller and the physical and media access layers. It also has an integrated write buffer and frame sync controller.

When the device receives data from the network, it stores the data in the 8K or 32K-byte receiving buffer. The write buffer is then used to transfer the data to the sending buffer. The frame sync control logic receives the frame synchronization signal from the write buffer and starts transferring the data to the sending buffer. Once all of the data is transferred to the sending buffer, the device sends the data back onto the network.

The device also has an integrated Ethernet switch, which enables the device to switch between multiple physical ports. This provides the flexibility needed to connect multiple devices to the same network and to establish a complete local area network.

The integrated chip-to-chip interface enables two or more devices to be connected together. This feature allows the devices to communicate with each other and to transfer data faster than is possible with Ethernet. The device also supports multiple address buses to enable communication between multiple devices.

Conclusion

The KSZ8692PBI is an integrated 10/100 Ethernet transceiver, media access controller and physical layer transceiver. It is suitable for a wide range of embedded applications. It supports auto-negotiation and auto-polarity functions and can detect wire speed automatically. Additionally, it supports multiple packet filtering functions, making it an ideal choice for home networking, small- and medium-sized business networks and embedded applications.
