Introduction
CS8900A-CQZ is an interface-controller product developed by Cirrus Logic. It is used in embedded system design, including in-home and industrial applications. This article introduces the application field and the working principle of CS8900A-CQZ.
Application Fields
The CS8900A-CQZ is mainly used in embedded system design, including in-home and industrial applications. The operation of these applications requires high-performance and low-smoke networking. The CS8900A-CQZ can provide an interface-controller for reliable, low-cost, easy-to-use and low-power Ethernet connection. Furthermore, some other communication applications, such as Point-to-Point connection, voice and data transmission, also can work on it.
Working Principle
The CS8900A-CQZ consists of a 10Base-T/100Base-Tx PHY transceiver, a controller and a RAM buffer. The transceiver complies with IEEE 802.3 10Base-T,100Base-Tx standard, so it can provide the physical layer interface for the controller. The controller can detect the physical connection, establish communications and control the transmission, so it is the core of the CS8900A-CQZ. The RAM buffer is used to store the data sending and receiving by the controller, and it also strengthens the communication capability.
The CS8900A-CQZ works through the five stages: link detection, frame receiving, frame buffering, frame transmitting, frame acknowledgment.
- Link Detection: The controller detects the physical connection status.
- Frame Receiving: The controller temporarily stores the data received in the RAM buffer and sends the addresses information.
- Frame Buffering: The controller parses the data and buffers the valid data.
- Frame Transmitting: The controller sends outgoing frames.
- Frame Acknowledgment: The controller confirms that the transmission is successful.
The CS8900A-CQZ contains integrated peripheral circuitry, such as eight DMA channels, one UART serial controller, interrupt controller, clock management circuitry etc. These integrated circuits can provide the necessary interface for communicating with other devices.
Conclusion
CS8900A-CQZ is an excellent interface-controller product developed by Cirrus Logic. It is mainly used in embedded system design, providing high-performance, low-smoke, low-power and easy-to-use Ethernet connection. Furthermore, it also supports various communication applications, such as Point-to-Point connection, voice and data transmission, which making the systems more powerful.
