Dear All,
After hours of reading the posts as guest, I decided to post to request your help.
Here my issue : I want to connect a Sony TVset KDL32EX711 to an Arcam rDac. The TVset has only a Toslink digital output, no coax.onboard
The real issue is the distance between the rDac and the TVset : 13 meters (39 inches).
The attenuation is too high along the cable and the DAC is detecting no source. I tested also with another source. This is the same result. I sent back the cable to the manufacturer for testing and polishing, there was no more results.
After diging into the Toslink specification, I discovered the audio toslink modules are made for 5 meters transmision (TOTX147 series) or 10 meters transmission (TOTX177 series). The needed cable is 13 meters ahead of that.
In order to make this working, I would make one "Toslink extender" which allow higher transmission distance. However, I am not that much qualified in electronics.
The main idea is using the couple IF-E98 and IF-D97
Those modules allow 75 meters transmission & up to 50 Mbits/s. This should be enough. One 74ACT08 logic gate between the 2 optic modules would clean the signal.
The overall propagation time between the input and output is 12ns + 10 ns + 7 ns. This means a total of 29ns delay in the optic channel.
Do you think it will weak the signal and make the music worse ?
Do you think this would work ? Do you have any other idea ?
Thank you for your help
