The 8090 is an HD/SD universal input 12-bit analog to 10-bit SDI converter. The 8090 accepts HD component and SD component, composite and Y/C. Differential analog inputs are used for common mode noise rejection. A 5-line adaptive comb or notch filter is used for Y/C separation in composite SD mode. SD inputs are oversampled to 54 MHz and the output circuitry includes a VCXO filter to reduce jitter. The unit offers full user digital proc control, with user memory, that provides adjustment of white level, black level, color gain, and color phase.
