AJA D10AD 10-bit Component/Composite to SDI Converter User Manual — Introduction

Introduction

The D10AD provides excellent quality 10-bit conversion of component or

composite analog video to SDI—with EDH. The D10AD accepts YPbPr (SMPTE,

EBU-N10), Betacam, or RGB component inputs and NTSC/PAL or YC (S-Video)

composite inputs. When using composite sources, the D10AD offers a 4-Line

Adaptive Comb Filter for high quality decoding. The comb ﬁlter can be switched to

2-line or notch modes for minimum delay requirements. NTSC/PAL conﬁguration

is automatic. Video format, AGC, H/V blanking, and pedestal are all user

conﬁgurable via dipswitches.

Note:

The D10AD requires a Time Base Correct source. Operation is not

recommended from VTRs, laser disks, etc., without Time Base Correction (TBC).

User Controls

The user interface for the D10AD 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 comb ﬁlter, EDH, AGC, and

test pattern.

Switches 1 and 2 select composite or

component input and the type of component

input. Switches 3 through 8 set conﬁguration

features. The exact function of each DIP

switch and what it controls is described on the

following pages.

Note:

Changing input format (SW1, SW2, or SW3) causes a reset to occur that

takes about 10 seconds to complete.
