AJA R20AD 10-bit Universal Decoder User Manual
The AJA R20AD provides excellent-quality 10-bit conversion to SDI from
component or NTSC/PAL sources. The R20AD accepts YPbPr (SMPTE, EBU-N10),
Betacam, or RGB component inputs and NTSC/PAL or Y/C (S-Video) composite
inputs. Featured in the R20AD is a 4 Line Adaptive Comb Filter for high quality
decoding of composite sources. The comb filter can be switched to 2-line, or
notch modes for minimum delay requirements. The R20AD also accommodates
an optional FSG card (Frame Sync) for synchronizing the output video relative
to an external reference. NTSC/PAL configuration is automatic. Video format,
AGC, H/V blanking, and pedestal are all user configurable.
The R20AD is a 10.3” X 3.1” card, designed to plug into The AJA Video FR1-1 RU
frame and the AJA Video FR2-2 RU frame.

FR1 and FR2 BNC Connector Assignments, R20AD Card Module
When the R20AD module is installed in an AJA FR1 or FR2 frame, a corresponding
group of 9 BNCs on the rear panel then provide I/O for the module. The
illustration above shows the connector assignments for both the FR1 and FR2
when used with the R20AD.
Note:
See the topic “ External Reference Information ” later in this manual for
information on use of the Ref Loop BNCs versus the FR1/FR2 frame reference BNC
when connecting an external reference video signal.

AJA R20AD 10-bit Universal Decoder User Manual
The user interface for the R20AD consists of a 16-position hex
rotary switch, a momentary action up/down toggle switch,
and 6 LEDs that indicate status. The rotary switch selects a
function or setting to be controlled by the toggle switch. The
BANK LED (LED 1) shows which of two banks of functions are
to be accessed. The LEDs are numbered 1-6 from top to
bottom or left to right. The LEDs are labeled as follows:
The following tables describe the functions controlled by the user interface. To access a
particular function, set the hex rotary switch to the appropriate function, and then use
the toggle switch to adjust the selected function. For on/off type functions, such as
Setup/NoSetup selection, move the switch to the UP/LEFT position to set the function
or move the switch DOWN/RIGHT to clear the function. Multi-value functions such as
INPUT MODE will rotate through the possible choices for the function. To control
variables, such as framesync delay, the value of the function will be incremented or
decremented each time the switch is momentarily moved either up, or down
respectively. Holding the switch in either position causes the function to automatically
increment or decrement, after a two second pause. With functions having more than
two selections, the toggle switch cycles through the available selections.
Note:
for input format selection, select either composite or component (function 4)
before selecting between types of composite or component (function 5).
