Hi to all,
Hi Radiotvnut,
Please have a look at this recent ARF TV section thread.
I published the complete data, including PCB files for a Video-rate Opto-isolator.
A HCPL4562 high speed opto-isolator is used, 17MHz bandwith at -3dB.
The circuit was created by Avago and available as a limited supply module about a decade ago.
It is unavailable now, hence the re-creation.
The Opto-IC is still current (Digikey, Mouser...).
The BroadCom suggested buffer has been added for low impedance video output as the Avago eval board is a high impedance output.
