Default Optical Add-on?

Open question for the TwistedPear crew.
Have you considered an optical add-on module for the S/PDIF 4:1 MUX/Reciever module?
Something with Toslink/optical inputs and outputs?
Maybe a way of going from Toslink to regular S/PDIF and S/PDIF to Toslink?

I think this kind of product would compliment the rest of your line of products.

Yes, it doesn't provide optical output.

You could easy swap the receiver module with a transmitter module.

A quick google - Toslink Transmitter Receiver Optical Modules TX / RX; High Speed Signal Transmitter / Receiver (8Mbps, NRZ signal)

and

Toshiba Fiber Optic Transmitters, Receivers, Transceivers

Sorry - You were asking the TP guys - I'll back off...

Sure, I could solve it myself.
I started the thred to see if they had thought about it. Hopefully I'm not the only one who think it would be a handy little addon.
I'll have my own problem solved long before any product could possibly be made available.

Thanks for the links though.

Was wondering about the ability to interface this toslink module to a Behringer DCX2496. The input is transformer coupled to a 110 ohm termination resistor then to the input of the CS8420. It is rated for SPDIF input, though with the 110 ohm resistor is really designed for AES.

I noticed the TP module is not equipped with any source resistor. In my application I will be interfacing the module to the factory ribbon cable wires, so distances involved are measured in inches. I can use the DCX power supply to provide 15V power to the module, if the on board 3.3V regulator wouldn't get too hot.

I'm thinking this should work just fine. What do you think ?

Should be ok, the le<xx> has a max input of 20v.

OR you could use an intermediate reg. to drop the voltage before hitting the TOSLINK module.

Changed my mind, I'll just use the 5V power supply to feed the TP Toslink module.

Russ, any idea when these will be back in stock ?

If you have boards, I can do the rest myself... these will fit perfectly in the DCX behind the power supply.
