Interface - Drivers, Receivers, Transceivers

The MAX1485EUB+ is a robust and low-power transceiver IC from Maxim Integrated. It was initially released in 2008 and its primary application field is communications systems that require differential signal lines. The MAX1485EUB+ is capable of communicating high-speed data in both directions and is compliant with the current standards for IEEE 1394 and USB 1.1 communications. This article will examine the application field, the operation principles, and the characteristics of the MAX1485EUB+.

Application Field

The MAX1485EUB+ was designed primarily for applications in high-speed communications networks. It is perfect for I/O ports, firewire & USB 1.1 applications. It contains two integrated 20MA (200 Ohm) drivers and two 10-bit receivers, which allows for simultaneous communication of high-speed, bi-directional data. Moreover, the MAX1485EUB+ is compliant with the IEEE 1394-1995 and the USB 1.1 standards, making it an ideal tool for communication networks that require compliance with such standards.

Working Principle

The MAX1485EUB+ incorporates several features that make it suitable for usage in high-speed communications networks. Firstly, the integrated 20MA (200 Ohm) drivers are capable of transmitting data at rates up to 5Gbps, while the 10-bit receivers are capable of receiving data at rates up to 3Gbps. Additionally, the MAX1485EUB+ contains two integrated phase-locked loops (PLLs) which are responsible for clocking signals, thus ensuring the smooth communication of data between two devices without any interruptions. Furthermore, the MAX1485EUB+ also contains an adaptive edge rate control (ERC) and a pre-emphasis filter to reduce signal loss and timing jitter, respectively.

Characteristics

The MAX1485EUB+ possesses a number of characteristics which make it suitable for use in communications networks. Firstly, it has low power consumption, with a typical power consumption of just 500mW. This makes it ideal for applications that involve battery operation, as it minimizes the amount of energy consumed. Additionally, the MAX1485EUB+ has low EMI emissions and utilization for RFI/EMI-protection purposes. Lastly, the MAX1485EUB+ has excellent bit-error rate (BER), making it reliable for communication of sensitive data.

Conclusion

The MAX1485EUB+ is a robust and reliable transceiver IC that is perfectly suited for applications in high-speed communications networks. It contains two integrated 20MA (200 Ohm) drivers and two 10-bit receivers, and is compliant with the current IEEE 1394 and USB 1.1 standards. Furthermore, it has several advantages including low power consumption, low EMI emissions, and excellent BER.
