EDH-6800-2 EDH Detection/Insertion Serial Distribution Amplifier Module

Overview

EDH analysis is not currently available for 360 Mb/s mode.

The EDH-6800-2 is a versatile serial distribution amplifier that also functions as a digital video Error Detection and Handling (EDH) check word analyzer and decoder. As a distribution amplifier, it provides equalization and reclocking to eight serial outputs. As an EDH analyzer/ inserter, it can detect errors on input signals that contain EDH information and/or insert EDH into signals where it does not already exist.

The EDH-6800-2 functions with composite (143 Mb/s), component (270 Mb/s), and the proposed 16:9 (360 Mb/s) standards.

With EDH recognized as a method of verifying serial signals for impairments, the EDH-6800-2 offers a compact and cost-effective way of monitoring EDH in serial links without using expensive laboratory analyzers. It also provides the means to “inject” EDH check words into serial digital video signal paths. With its eight equalized and reclocked outputs, the EDH-6800-2 can also be used within a system in place of a serial distribution amplifier, with the added benefit of EDH.

Controls and indicators provide a comprehensive set of analysis functions. With them, EDH encoding on the output signal can be turned on or off and input presence and status are indicated. An on-board audible alarm can be enabled to alert the user to input signal EDH errors and an opto-isolated “contact-to-ground” signal can be used to interface to any external fault warning system.
