IRT Eurocard
Type HDA-4510
1.485 Gb/s HD 6 O/P
Reclocking Distribution Amplifier
General Description
The HDA-4510 1.485 Gb/s serial digital video reclocking distribution amplifier provides the user with a single
standard module to cover a wide range of distribution and monitoring functions for High Definition (HD) digital
signals.
As well as accepting an HD signal, the HDA-4510 will also accept Standard Definition (SD) rates such as SDI. ASI
is also possible, however as three of the six outputs are inverted only the non-inverted output ports are suitable for
ASI.
Serial digital signals suffer severe deterioration over relatively short cable distances. This is especially so with the
HD high data rate. The HDA-4510 provides a means of extending the working distances that can be achieved by
equalising and re-transmitting the data mid route.
The HDA-4510 will automatically reclock either a 1.485 Gb/s HD signal or a lower rate SD signal and automatically
adjust the output driver slew rate to suit.
Front panel LEDs indicate when an input signal is present and also whether it is either an HD or SD type of signal.
A relay alarm output, with a selectable N/O or N/C switch to ground contact, is available for indication of loss of
input signal or loss of power.
An optional SNMP (Simple Network Management Protocol) plug in module is available for remote monitoring when
used in conjunction with IRT’s 4000 series frame fitted with SNMP capability.
The HDA-4510 is designed to fit IRT’s 4000 series frame for use with IRT’s SNMP system as well as being suitable
with IRT’s Standard 1000 and 3000 series Eurocard frames and may be used alongside any other of IRT’s analogue
or digital Eurocards.
