Analog Devices: CN0256 Reference Design for Isolated LVDS Interface Circuit

Kit Overview

 

Low voltage differential signaling (LVDS) is an established standard (TIA/EIA-644) for low power, high speed, point-to-point communication. It is used in instrumentation and control applications to send high volumes of data across backplanes or short cable links, or to distribute high speed clocks to different parts of an application circuit.

 

The EVAL-CN0256-EBZEVAL-CN0256-EBZ circuit demonstrates isolation of an LVDS interface. Advantages of isolating LVDS interfaces include protection against fault conditions (safety isolation) and improving robustness (functional isolation).

 

The ADuM3442ADuM3442 provides digital isolation of the logic inputs to the ADN4663ADN4663 LVDS driver and the logic outputs from the ADN4664ADN4664 LVDS receiver. Together with provision of isolated power using the ADuM5000ADuM5000, a number of challenges to isolating LVDS links in industrial and instrumentation applications are met.

 

Isolated LVDS interface circuit isolating two transmit communication channels (CMOS/TTL to LVDS) and two receive channels (LVDS to CMOS/TTL). The signals can be isolated at data rates up to 150 Mbps while maintaining the ADUM3442CRWZADUM3442CRWZ specification for maximum pulse width distortion.

 

Logic signals can be applied to IN1 and IN2 and are isolated by the ADUM3442CRWZADUM3442CRWZ. The corresponding outputs of the ADuM3442 (the DIN1 and DIN2 test points) are connected to the ADN4663ADN4663 LVDS driver to create LVDS signals on DOUT1+, DOUT1− and DOUT2+, DOUT2−.

Key Features for EVAL-CN0256-EBZEVAL-CN0256-EBZ Evaluation Board are as below:

  • A number of challenges to isolating LVDS links in industrial and instrumentation applications are met that include the following:
    • Isolation of the logic signals to/from the LVDS drivers/ receivers,
      • ensuring standard LVDS communication on the bus side of the circuit.
    • Highly integrated isolation using just two additional wide-body SOIC devices,
      • Tthe ADuM3442ADuM3442 and ADuM5000ADuM5000,
      • To isolate the standard LVDS devices.
        • The ADN4663ADN4663 and ADN4664ADN4664.
    • Low power consumption compared to traditional isolation (opto-couplers)
      • Low power operation is a feature of LVDS applications.
    • Multiple channels of isolation.
      • In LVDS applications, parallel channels are used to maximize data throughput.
    • High speed operation; the isolation can operate at up to 150 Mbps, facilitating basic LVDS speed requirements
