The 6540 provides 10-bit 270 Mbit SDI SMPTE 259M conversion to analog composite, Y/C and component YPbPr and RGB. The 10-bit encoding engine oversamples 4:2:2 to 4:4:4 for internal processing and then 4x oversamples outputs to 16:16:16 for improved signal performance. An internal VCXO with de-jitter loop filter to 2Hz reduces digital jitter before the encoding process. Full user processing controls, with user memory allows adjustment of white level, black level, color gain, color phase (color phase on composite and Y/C), gamma and digital noise reduction.
