Introduction

AJA D10CE 10-bit SDI to Component/Composite Converter User Manual — Introduction
The D10CE converts Component Serial Digital (SDI) to analog Composite and
Component outputs—simultaneously. Four analog outputs are provided, plus two
equalized and re-clocked SDI loop-through outputs. The D10CE automatically
detects and configures to 525 or 625 line component digital input and then outputs
analog NTSC (525 line input), PAL (625 line input) or component as configured by
an 8-section DIP switch.
The full dynamic range of input component video values, below black and above
white, are not clipped when the D10CE encodes. When the D10CE is in its NTSC
mode, the 7.5 IRE pedestal can be disabled by DIP switch selection.
The component and composite outputs incorporate optimum chroma filtering and
independent pedestal configuration. An exclusive PLL jitter filter/memory reduces
the effects of SDI jitter on the output analog video. This feature, along with the
precision 4x oversampled D/A filters, provides high quality analog outputs, with very
low phase noise in the composite outputs.
High quality 10-bit encoding, 4 times oversampling

The user interface for the D10CE is an 8-switch DIP
accessible through a cut-out in the bottom of the
unit. Use the DIP switches to configure outputs,
pedestal, blanking, and enable or disable noise
reduction.
Switches 1 through 3 control the COMPOSITE/
SYNC output BNC. Switches 4 through 8 control
the video format of the three BNCs below. The exact
function of each DIP switch and what it controls is
described on the following pages.
