Crystal Vision Introduction

DDA208B User Manual R1.0 2 24/05/05

1 Introduction

The DDA208A is a dual non-reclocking serial digital video and ASI distribution amplifier

with up to four outputs per channel. It has auto-equalisation for up to 250 metres of

coaxial cable.

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 the rear. Depending on

frame design, a hinged or removable front panel reveals LED indication of input and PSU

status when opened.

DDA208A dual non reclocking ASI/SDI distribution amplifier

The single slot rear connector provides two DVB-ASI compliant serial digital outputs per

channel with 12 modules in 2U of rack space. Alternative rear modules provide more

outputs but with fewer modules per frame.

It may be used with the RM01 single slot rear connector, the RM02 quadruple slot rear

connector or the RM18 double slot rear connector. The RM18 provides access to all four

outputs per channel, with 6 modules in 2U of rack space.

Further rear connector details may be found in the Installation chapter.

DDA208B User Manual R1.0 5 24/05/05

3 Hardware installation

The DDA208B digital video distribution amplifier fits into all Crystal Vision rack frames.

All modules can be plugged in and removed while the frame is powered without damage.

Universal rear connectors

When used with a single height rear connector, the 2U Indigo or FR2AV frame will house

up to 12 modules and dual power supplies, the 1U Indigo or FR1AV frame will house 6

modules and a single power supply. The 1U Desk Top Box has a built-in power supply

and will house up to 2 modules with a single height rear connector.

The 2U and 1U frames have a hinged front panel which gives 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 DDA208A may be used with the RM01 single slot rear connector, the RM02

quadruple slot rear connector and the RM18 double slot rear connector.

General purpose interface

The external GPI control lines 'a' to 'f' at the frame remote connectors are provided to

allow remote control and/or remote status indication. Line 'a' is assigned as a GPI output

to provide remote indication of input presence.

GPI lines are pulled up to +5V through 6k8 Ohm, 270 Ohm series resistor so they can

drive an LED directly. If the series resistor is shorted out, the GPI output can drive a bulb

at +45V 100mA max.
