3415omponent Video Digital to Analogue onverter

1Introduction
he 3415 is a precision 10 bit 270Mb/s component digital to analogue video
converter with full I U-R 601 filtering. he output is switchable for GBR or Y, Pb, Pr
with sync on Y/GBR and on a separate output. An output of composite analogue
video is provided to facilitate composite monitoring and four re-clocked and
buffered copies of the SDI input are provided with the 30mm rear panel. Vertical
interval information may be passed or blanked and most configuration settings can
be remotely controlled or monitored via the COSMOS interface.
he features available are:
•three analogue component outputs plus sync and analogue composite
monitoring
•additional four re-clocked buffered SDI outputs with the 30mm K3415-3 rear
connector
•10 bit 270Mbit/s processing
•automatic 525/625 operation
•adaptive input equalisation
•variable/calibrated (N10) gain
•setup (pedestal) on/off in 525
•VANC (Vertical Ancillary Data) deletion on/off
•COSMOS equipped

2onfiguration and operation
2.1Selecting the rear connector
he 3415 may be used with either the 20mm K3415-2 rear connector or the 30mm
K3415-3 rear connector which provides four outputs of the re-clocked buffered SDI
input.
Please refer to the installation chapter for help with installing modules and rear
connectors into the ICON frame.

2.2Setting component output options
he analogue component output may be set in either Y, Pb, Pr or GBR formats. Syncs
may be added to the luminance (Y) or GBR signals and a 7.5 IRE pedestal may be
added in 525 operation to R, G, B and Y outputs.
he analogue outputs may be manually adjusted from front controls or left
calibrated according to SMP E/EBU N10. In addition the converter may be set to pass
or blank VANC (Vertical Ancillary Data). COSMOS allows many of these functions to
be controlled remotely.
he front control dip switch settings are shown in the following diagram and
summarised in the table below.

3Trouble shooting
The Input Error LED is lit
•check that a valid serial digital video signal is connected to the rear connector
input BNC
Video black level is raised in 525 mode
•check that the 525 PED switch is not on if 7.5 IRE set-up is not required
Output levels are incorrect
•for calibrated N10 levels check that the GAIN VAR switch is off
The output is not synchronised in downstream equipment
•check the syncs requirement of the downstream equipment and supply separate
syncs, syncs on green or syncs on luminance as appropriate
The Power LED is not lit
•check mains power to the frame is turned on
•if necessary check the PSU as explained in the power supply section
•check the card is plugged in securely
•check to see if one of the re-settable fuses has operated. o do this turn the
power off, wait for thirty seconds and then restore the power.
