![]() I'll look up the schematics for you some time today.Įdit: Ok, I just read Digitrax' post. That's why you have to use a VIDEO amp or other high bandwidth amplifier. It is designed for AUDIO signals, and word clock is not audio. Of course this spec doesn't necessarily mean that the device rolls off abruptly above 100kHz, but it might. How are you going to pass 192kHz word clock with this? This device will also probably filter your nice square wave 44.1kHz clock into a weird oblong sine wave. From the data sheet:įrequency Response: 10 Hz to 100 kHz (+/‑ 0.05 dB) Ummm, no, that's not what you're talking about. Also, do you happen to know what the output voltage it churns out is? What specific chip did you use? Maybe I could locate one NOS. It seems that video BNC repeaters are mostly regulated at 1 volt - because this is what has been established as standard in that medium.Īs everyone knows, no universal voltage standard exists for Digital Audio BNC Word Clock. Actually, I was going to ask about jury-rigging a video BNC amplifier for such a purpose. If you aren't really into DIY you'll be better off just buying one of these off the shelf somewhere.Wow - thanks for that info. If you aren't really into DIY you'll be better off just buying one of these off the shelf somewhere.ĭIY is rarely cheaper than buying off the shelf when you calculate in the time value of money and other factors. Unfortunately I can't locate the build pics but it's just a PSU and the heat sinked vid amp chip on a perf board.ĭIY is rarely cheaper than buying off the shelf when you calculate in the time value of money and other factors. I used a terrific (but now unfortunately obsolete) video amplifier chip because it had waaaaaay more bandwidth than needed for this application. Of course in stating this I am assuming that your power supply has enough current to satisfy demand and all the other obvious technicalities are well cared for. If the amp has enough bandwidth and your connections are terminated properly jitter won't be a problem. This is a very simple device to build, because it is merely a buffer/amplifier. I made my own word clock distributor a few years ago, when I needed to take the single output of my WC generator and distribute it to about 8 locations throughout the studio. ![]() It's not going to take luck, just a little skill.
