The LM2502SMX/NOPB serializer and deserializer (SERDES) is an industry-leading integrated chip which enables high-speed serial data links between endpoints. It is ideal for use in various applications, such as automotive infotainment, industrial control, high-speed networking, telecom, storage systems, and more. This article will discuss the application field and working principle of the LM2502SMX/NOPB.

Application Field

The LM2502SMX/NOPB is an 18-bit SERDES with a data rate up to 4 Gb/sec. It is ideal for use in applications that require high data transfer rates and low latency. Examples of such applications include high-speed networking, automotive infotainment, storage systems, and other industrial control systems. It features a low power consumption, a low-voltage operating mode, and a high-bandwidth bidirectional serial interface. The device also includes enhanced features such as crossbar switching, site-wide synchronization, and power management. Additionally, the LM2502SMX/NOPB supports point-to-point links and can be used to connect several endpoints with a common clock rate.

Working Principle

The LM2502SMX/NOPB utilizes a differential-receiver-transmitter pair to transmit and receive data over a single lane. The first components of the SERDES are the receiver and the transmitter. The receiver converts incoming state-directed serial data streams into parallel information, which is then passed to the deserializer. The deserializer then interprets the information and passes it along to the corresponding receiver. The transmitter receives parallel information from the serializer and converts it into state-directed serial data streams for the receiver. The receiver then interprets the data and passes it along to the corresponding transmitter.

The LM2502SMX/NOPB also features digital-equalization that reduces the amount of noise encountered in the signal path. This helps ensure that the data transmitted and received is accurate and free from distortion. It also features a built-in AEC-Q100 compliant error-correction code (ECC) to further minimize potential data errors. The device also supports clock-data recovery (CDR) and clock-data synthesis (CDS) to enable synchronization between the receiver and transmitter.

The LM2502SMX/NOPB SERDES also supports jitter-tolerant operation and has a very simple power-saving architecture. The chip is capable of automatically detecting energy savings opportunities, which are triggered by non-data modes. In addition, the device has low-power initialization capabilities, allowing it to initiate and shut down quickly without significant power consumption. This makes the LM2502SMX/NOPB an ideal solution for various low-power applications.

In conclusion, the LM2502SMX/NOPB serializer and deserializer (SERDES) is an industry-leading integrated chip which enables high-speed serial data links between endpoints. It is ideal for use in automotive infotainment, industrial control, high-speed networking, telecom, storage systems, and more. The device features a low power consumption, a low-voltage operating mode, a high-bandwidth bidirectional serial interface, enhanced features such as crossbar switching, site-wide synchronization, and power management. It also supports point-to-point links and jitter-tolerant operation. Furthermore, it has a very simple power-saving architecture and low-power initialization capabilities.
