Toslink Repeater/Splitter
-
The purpose of this circuit is not only to extend an optical digital audio connection (Toshiba Toslink) but also to function as a splitter, so that two devices can be connected to one Toslink output.
The circuit consists of the standard application for the Toslink receiver module TORX173 (IC1) and the Toslink transmitter module TOTX173 (IC2 and IC3), that we have used on previous occasions.
