USM-6800 PAL/NTSC Monitoring Encoder Module

Overview

The USM-6800 offers the combination of a 4 output NTSC/PAL encoder and a 4 Output serial distribution amplifier. It is capable of removing jitter from the 4:2:2 serial signal before encoding and conversion to analog. The result is a clean composite analog signal which also maintains zero SCH. Automatic switching based on the input line rate of 525 or 625 lines is provided.

The USM-6800 can also be configured to provide RGB, YUV or YC outputs. When RGB or YUV are selected, three of the output BNCs provide the component signal, while the remaining BNC still provides composite analog.

When YC is selected, two of the outputs are switched to YC, the other two remaining NTSC or PAL, depending upon the line standard in use. An optional adaptor, which plugs into the rear BNCs, provides a standard YC connector. The four serial digital outputs are always present.

Specifications and designs are subject to change without notice.
