The 6590 provides analog to 10-bit SDI conversion. The 6590 accepts composite, Y/C and component YPbPr analog input signals and outputs 270 Mbit SDI SMPTE 259M. Differential inputs are included for ground loop rejection. A 4- or 3- line comb or notch filter is user-configurable for Y/C separation in composite mode. An output jitter VCXO reduces 270 Mbit jitter down to 2Hz. Full user proc control, with user memory, allows digital adjustment of white level, black level, color gain, and color phase.
