1Introduction
The DDAA132 is an 8 bit serial digital to analogue composite converter with reclocked
serial and up to four selectable composite or Y/C analogue outputs.
The universal connection system allows a mixture of Crystal Vision modules in the frame.
The modules plug in the front, and the rear connectors plug in at the back. Depending on
frame design, a hinged or removable front panel reveals LED indication of input and PSU
status when opened.
DDAA132 serial digital to analogue converter
The DDAA132 may be used with the RM01 single slot rear connector, the RM02
quadruple slot rear connector and the RM18 double slot rear connectors. The RM01
allows the highest frame packing density, with reduced output connections, whilst the
RM02 and RM18 provide access to all outputs but with reduced packing density.
The RM01 allows 24 modules in a 4U frame, 12 modules in 2U, six in 1U and two in a
desk top box. The RM02 allows 18 modules to fit in a 4U frame, 9 modules in 2U frame
and the RM18 allows 12 modules in a 4U frame, six modules in 2U frame, three in 1U
and one in a desk top box.
The analogue outputs can be switched between input video and an internal test pattern
under local or remote (GPI) control. DDAA132 accepts either 625 or 525 line input, with
automatic detection.
To produce the internal Luma/Chroma test pattern, the DDAA132 requires a valid SDI
input signal from which to extract clocking information.
Crystal Vision Introduction
13/01/05 4DDAA132 User Manual R7.2
The available test pattern is:
•Luma/Chroma Ramp
The main features are:
•8 bit serial digital to analogue composite converter
•Variable gain
•Automatic equalisation for up to 200 metres of coaxial cable
•Up to four reclocked SDI outputs and four composite or two Y/C outputs
•GPI/LED input presence indication
•Auto or manual PAL 625/NTSC 525 line selection
•VBI blanked or unblanked
•Modulated ramp test pattern or serial input
•NTSC setup on/off and chroma bandwidth select
•Card edge control
Note: This manual covers the DDAA132. The DDAA132P with a greater range of internal test
patterns, including PLUGE is also available, along with a dedicated manual.

2Hardware installation
The DDAA132 serial digital to analogue composite converter fits into all Crystal Vision
frames. All modules can be plugged in and removed while the frame is powered without
damage.
2.1 Universal rear connectors
When used with a single height rear connector, the 4U Indigo frame will house up to 24
modules and up to three power supplies, the 2U Indigo frame will house up to 12 modules
and dual power supplies, the 1U Indigo frame will house 6 modules and a single power
supply. The desk top box has a built-in power supply and will house up to two modules
with a single height rear connector.
The 4U, 2U and 1U frames have hinged front panels which give access to the PSU and all
modules. The desk top box has a removable front. The universal frame wiring system
allows any of the interface range of modules to be fitted in any position with the use of
removable rear modules.
The DDAA132 may be used with the RM01 single slot rear connector, the RM02
quadruple slot rear connector and the RM18 double slot rear connector.

2.2 General Purpose Interface
The external GPI control lines 'a' to 'f' at the frame remote connectors may be used to
control the DDAA132 remotely with (say) remote switches emulating some of the front
panel switches. The GPI lines are normally pulled up on-board to +5V via 10kΩ and will
withstand up to +35V.
