LE88231DLC Application Field And Working Principle

The LE88231DLC is an integrated circuit (IC) from ON Semiconductor based on the ISO/IEC 8851-1 standard that is designed for 10/100Mbps Ethernet communication. Its functional elements include line coding, DPLL, clock frequency offset calculation, clock and data recovery, memory control, reset control, link status monitoring, and FIFO interface. All of these components are covered by the same package, making it a very practical and efficient solution for 10/100Mbps Ethernet applications. Additionally, the LE88231DLC includes several supporting features, such as equalization, adaptive equalization, spreading ratio adaptation, and low latency receive mode.

The LE88231DLC is particularly suitable for 10/100Mbps Ethernet applications. It\'s a low power device, enabling it to be used in a variety of mobile and wired applications, including personal computers, mobile phones, networking applications, and set-top boxes/gateways. It supports a wide range of media access control (MAC) and physical layer (PHY) protocols, such as SONET, SMDS, and CSMA/CD. Additionally, the LE88231DLC is compliant with the 10/100Mbps Ethernet standard, providing the best performance for full duplex and half duplex communication.

The LE88231DLC is designed to meet the industry\'s best practices in 10/100Mbps Ethernet communication. Its integrated symmetric phase-locked loop (PLL) is capable of extracting and regenerating accurate phase signals from incoming data streams. Additionally, the device includes an integrated continuously variable spread spectrum clock (CVSSC) that is capable of suppressing EMI noise while providing low power consumption and a low noise output.

The working principle of LE88231DLC is based on transceiver techniques. It receives, transmits and provides a physical layer interface between a local and remote device. It provides the necessary functionalities to connect a device to a physical network. The core components of LE88231DLC are the CPU and the FIFO memory interface that enables the transmission of data. It supports 10BASE-T and 100BASE-T Ethernet with 10MB and 100MB pulse-width modulation (PWM) for communication.

The first step of the LE88231DLC is to receive data from the local device. This is done by the transceiver that converts the data from the local device into digital signals. These digital signals are then stored in the FIFO memory interface. This data is then processed, encoded, and transmitted to the remote device. The transmitted signal is then received by the receiver, demodulated, and decoded. This process is repeated for the transmission and reception of data.

The LE88231DLC also has several additional features that enable it to provide reliable and efficient communication. These include source synchronous clock signals, clock and data recovery, low jitter clock synchronization, and adaptive equalization. Additionally, the device is capable of supporting a wide range of signal types, such as Sinusoidal, Pulse Code Modulated (PCM), Quadrature Amplitude Modulated (QAM), and Frequency Division Multiplexed (FDM).

In conclusion, the LE88231DLC is a highly integrated IC based on the industry’s best practices for 10/100Mbps Ethernet communication. It is well suited for applications in personal computers, mobile phones, networking applications, and set-top boxes/gateways. It features an integrated PLL and CVSSC along with several other features that enable reliable communication. Additionally, the device is compliant with the 10/100Mbps Ethernet standard, providing the best performance for full and half duplex communication.
