Page 8 Revision 1.0
2.1.4. DA3A Connector
Description
Re-clocked version of the HD/SD input signal applied to INA compatible with
SMPTE 259M and SMPT292M.
Connector
Mini DIN 1.0
Impedance
75 ohm nominal
Return Loss
> 15 dB to 1.5 GHz
Signal Level
800 mV nominal
DC Offset
0 V ± 0.5 V
Rise/Fall Times
740 ps nominal for SD-SDI outputs
200 ps nominal for HD-SDI outputs
2.1.5. DA4A/GEN Connector
Description
Dual function and bi-directional. When configured to be an output using VLPRO,
a re-clocked version of the HD/SD input signal applied to INA will be generated
on this output and will be compatible with SMPTE 259M and SMPTE 292M.
When configured to be an input using VLPRO, the module will accept a bi-level
black reference genlock input that can be utilized as a reference for Path 1 and
Path 2. Note that when this input is configured to be a reference input, the
DA2A/6 Hz BNC will also be configured as an input. Applied reference must be
bi-level reference black only.
Connector
Mini DIN 1.0/2.3
Impedance
75 ohm nominal
Output Signal Level
800 mV nominal
Output DC Offset
0 V ± 0.5 V
Output Rise/Fall
Times
740 ps nominal for SD-SDI outputs
200 ps nominal for HD-SDI outputs

2.1.6. PGM1A-4A Connector
Description
Program outputs #1 through #4 for processing Path 1. When configured
using VLPRO to output SD-SDI signals, SMPTE 259M compatible signals
will be driven out of these connectors. When configured to output composite
video using VLPRO, NTSC/PAL analog video signals will be driven out
these connectors. Note that PGM1A and PGM2A are linked together as a
pair when setting the output-operating mode. In addition, PGM3A and
PGM4A are linked together when setting the output-operating mode.
