NEW DESIGN! LOOK FURTHER DOWN ONE THE PAGE
We are two students which have the following task/project:
We're developing a product for a fish farmer. Out in the sea, where the fish are held, there are two cameras. One camera is mounted at the top, its' task is to oversee the feed process.
The other camera is a sub sea camera, and its' tasks are; oversee the feeding process, the owner can see when the fish are finished eating.
The other task is just to monitor the fish, detect dead fish or diseases.
Our circuit board uses these two composite signals from the cameras, these go into a picture-in-picture (PiP) IC, PVP9390A.
This IC makes one single signal out of the two signals and this signal is sent wireless onshore.
We also use an Atmega64 to send I2C commands to the PVP9390A, we will have pushbuttons onshore, which sends different commands to the PVP9390A.
As you see in the schematic the PVP9390A gives out RGB, therefore we use the AD725 to convert it to composite.
The schematic is not totally finished, PIN3 at the AD725 should have a crystal oscillator, and this will be put in the schematic later, after we have found the correct one.
The EL1883 is a sync separator, which gets the horizontal and vertical sync (we’re hoping).
If we are unclear about anything feel free to ask. The attachments are the different datasheets.
Hope someone can overlook the schematic, and see if you see some obvious mistakes, first time using eagle, so be gentle
