We designed an image registration and synchronization circuit board. This board synchronized digital image addressing lines with an external sync pulse for proper placement of the image data, even when several sync pulses were missing. Offset registers allowed for circumferential image registration adjustment. Altera EP610 programmable logic devices (PLDs) were used for most logic functions. The completed board had a 6U by 160 mm form factor and was fully Versa Module Europa (VME)-compliant.
