The General purpose, point-to-point data communications PIN-preamplifier combination is ac-coupled to a custom Replaces DLT/R1040-ST1 model transmitters and quantizer IC which provides the final pulse shaping for receivers the logic output and the Signal Detect function. Both the Data and Signal Detect Outputs are differential. Also, both Data and Signal Detect Outputs are PECL compatible, ECL- referenced (shifted) to a +5 V power supply. Package The overall package concept for the Data Links consists of the following basic elements: two optical subassemblies, two electrical subassemblies, and the outer housings as illustrated in Figure 1. * ST is a registered trademark of AT&T Lightguide Cable Connectors.The package outline drawing and pinout are shown in Figures 2 and 3. The details of this package outline and pinout are compatible with other data-link modules from other vendors.
