The TCD1304 has found a new home. In the datasheet for the CCD there’s a schematic for a typical drive circuit, and I’ve run it through Eagle and sent the files to DirtyPCBS who’ve produced eleven prototype boards.
The picture below shows a populated board. The IC is a hexinverter, which ..inverts the pulses sent to CCD. This means there are few timer polarity registers which must be inverted in the firmware.
It works and the few components reduce the noise somewhat, which is quite obvious on the scope:
The PSU was bought from a user on DIYaudio.
DirtyPCBS sent me eleven CCD pcb’s. I will keep three for myself, and the first eight people in the eurozone (sorry rest of the world, but it’s too much of a hassle to ship outside of the European Union) to send me 7€ +shipping will be the happy owners of the rest. Use the contact form on this blog for more information.
I will include a cable, the 2200Ω resistor, the hexinverter and the 2SA1015-Y transistor, but the rest of the components I don’t have in excess.
Here are the Eagle files.
