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.
