MAX3086CSD Application Field and Working Principle

Introduction: The MAX3086CSD is a high-speed differential signal driver and receiver designed to support low-voltage differential signaling (LVDS) applications over long signal paths. It is ideal for applications where systems require high-bit reliability, low-noise sensitivity, and/or wide signal bandwidth. It features differential signal paths with 35-45 Ω source and receive termination for optimal signal integrity. The MAX3086CSD consumes only 1.3mA and 700mW of power, making it an efficient solution for applications where power consumption and system space are limited.

Classification

The MAX3086CSD belongs to the interface - drivers, receivers, transceivers category.

Application Field

The MAX3086CSD is primarily used in high-speed differential signal applications such as video/audio, high-resolution PCIe/XAUI, RS-485, PCI express, SATA and other types of differential signaling technologies. It can also be used in applications like high-speed Ethernet and Optical Networking.

Working Principle

The MAX3086CSD supports a differential signal path with a 35-45 Ω source and receive termination to minimize signal distortions. The input is AC-coupled and the bus is controlled with 28mV thresholds for end-to-end voltage detection. The MAX3086CSD converts a differential signal from the source to a single-ended signal and then back to a differential signal for output.

The MAX3086CSD also supports a lightweight 8-bit CRC method for error detection and correction which is used to ensure reliable data transmission and reception. The CRC is calculated on a bit-by-bit basis and stored in an internal register at the time of transmission and checked at the receiver. If the incoming data matches what is stored in the register, the data is accepted as true data, otherwise, it is rejected.

Conclusion

The MAX3086CSD is an optimal solution for applications requiring low-voltage differential signaling applications over long signal paths. It features differential signal paths with 35-45 Ω source and receive termination for optimal signal integrity, a lightweight error detection and correction mechanism, and low power consumption. This makes it a great choice for high-speed Ethernet and Optical Networking applications.
