It's a little expensive though, especially if you don't need all its video features. It will read and generate along with a few other functions. ICS2008B is a widely used LTC/VITC/MIDI chip. For my case small is good.Īlso, if anyone has more info on LTC-like interfaces, that would be most welcome! I have been able to find a couple, but they seem to come from the 80's and 90's, with high pin-counts packages and archaic 8-bit interfaces. I figured that I would need the OpAmp to make sure that the signal is +3.3v (the input goes from -1.7v -> +1.7v) and the Schmitt Buffer to get a nice clean square pulse.īut I want to know if anyone out there has any more information on LTC-generating devices, or if anyone knows of an ASIC that decodes accepts and decodes LTC and spits it out on SPI/I2C/UART.

The LTC output is a 3.3V peak-to-peak analogue signal, which I have a pretty good idea how to sample and decode - I was going to use an OpAmp followed by a Schmitt Buffer and feed that to my MCU.
Ideally I would be interfacing to something like the Ambient Lockit Sync Box, which has an LTC output. I'm making a widget that bolts onto a movie camera, and I want to interface to an LTC port.
