TP-145, TP-146 - Overview

3 Overview

The TP-145 and TP-146 are high-performance, twisted pair (TP) transmitter and

receivers for computer graphics video (including HDTV), unbalanced stereo audio,

and RS-232 control commands.

The TP-145 converts computer graphics video, unbalanced stereo analog audio,

and RS-232 control commands to a TP signal. The TP-146 converts the TP signal

back into computer graphics video, unbalanced stereo and S/PDIF digital audio,

and RS-232 control signals. The TP-145 and TP-146 together form a computer

graphics/audio/control data line transmitter/receiver system.

More specifically, the products feature:

 Resolution up to WUXGA 1920 x 1200

 HDTV compatibility

 EDID capture and status indication (TP-145)

 Simultaneous unbalanced stereo and S/PDIF (24-bit 48kHz) audio outputs
