3 AJA D5CE Serial Digital Encoder User Manual — Introduction
Introduction
The D5CE provides low cost, all digital conversion of SDI to either composite or
component analog video. Three analog BNC outputs are user configurable to cover a
wide range of format combinations including three composite, one composite and Y/
C, YPbPr (SMPTE, EBU-N10), Betacam, or RGB. The D5CE is useful for
monitoring video, level/phase checking, dubs, or desktop video applications. In
addition, an equalized and re-clocked SDI loop-through output is provided. The
D5CE automatically configures to 525 or 625 line component digital inputs and
then outputs analog NTSC (525 line input), PAL (625 line input) or component as
configured by the DIP switches.
The D5CE encodes the full dynamic range of input component video—values below
black and above white are not clipped. In the NTSC mode, the 7.5 IRE pedestal can
be disabled by the external DIP switch.
