1. Introduction
1.1 Module Description
1.1.1 IQSDA30
The IQSDA30 provides dual inputs with 3 outputs per input for distribution of HD-SDI 3 Gbit/s,
1.5 Gbit/s or 270 Mbit/s SD-SDIsignals in a single width package. Its 80m 3G, 180m HD input
equalization performance and non re-clocking distribution of wide-band signals make it ideal
for all distribution applications. For HD/SD only applications an HD/SD-SDI version is
available, with an option to upgrade firmware for 3 Gbit/s operation when required.
1.1.2 IQSDA32
The IQSDA32 is a distribution amplifier for HD-SDI 3 Gbit/s, 1.5 Gbit/s or 270 Mbit/s SD-SDI
signals providing 7 equalized and reclocked outputs of the input in a single width package. Its
80m 3G, 180m HD input equalization performance and non re-clocking distribution of
wide-band signals make it ideal for all distribution applications. For HD/SD only applications
an HD/SD-SDI version is available, with an option to upgrade firmware for 3 Gbit/s operation
when required.

to the input signal.
Channel 1 Bypass Yellow This indicator is illuminated when the signal on input
channel 1 is not being reclocked. That is, in reclock
bypass mode.
Channel 1 Error Red This indicator is illuminated when there is unknown or no
input on input channel 1..
Channel 1 Rate Green This indicator pair shows the rate on input channel 1 as
follows:
• Both LEDs illuminated – 3 Gbit/s

5.2 Input
The input screen enables the type of input signal to be selected.
5.2.1 Input 1 SDI Rate
•Auto: When selected, the unit will automatically detect and reclock any valid input
signal, and the detected rate will be displayed in the Unit Status.
If anything else is detected, the output will not be reclocked. If the On Input Loss /
Mute option is selected, the output will be muted; or, if the On Input Loss / Pass
option is selected, the output will be passed through.
•SD/DVB-ASI (270 Mb): When selected, the unit will reclock only SD/DVB-ASI (270
Mb) signals.
When selected, the On Input Loss controls are greyed out and are inactive. If any
other standard is applied to the unit the output will be muted.
•HD (1.5 Gb): When selected, the unit will reclock only HD (1.5 Gb) signals.
When selected, the On Input Loss controls are greyed out and are inactive. If any
other standard is applied to the unit the output will be muted.
•3G (3 Gb): When selected, the unit will reclock only 3G (3 Gb) signals.
When selected, the On Input Loss controls are greyed out and are inactive. If any
other standard is applied to the unit the output will be muted.
•Reclock Bypass: When selected, the unit will not reclock the input signal. If a
supported rate is detected, the Unit Status will display the detected rate, otherwise, ***
will be displayed.
If the On Input Loss / Mute option is selected, the output will be muted whenever a
recoginized rate is not detected; or, if the On Input Loss / Pass option is selected,
any signal standard, frequency, etc... will pass through.
