Page 14: The Gdk200 Card
4. The GDK200 Card Introduction The GDK200 is an advanced keyer platform for use in transmission applications. Especially where a full master control unit is overkill, these cards can be a cost and space-saving alternative. These units have 4 triple rate (all SD, HD, 3Gb/s capable) inputs: 2 background inputs, 1 fill input and 1 key input. It also has 4 triple rate outputs: 2 program outputs and 2 preview outputs. - Page 15 INSTALLATION AND OPERATION MANUAL Applications The GDK200 can be used as: • an entry level program output processor for basic program channels. • a production (3Gb/s) mixer/2D-DVE for live applications, e.g. sports events. Block Schematic Synapse GDK200 | 4. The GDK200 Card |...
- Page 16 Important Notice About Input Specifications The GDK200 does not have a built-in frame synchronizer. Therefore it is up to the system engineer to synchronize the inputs before feeding them to the keyer card. All inputs have to fall within the following specifications: 1080p 1000 pixels (6.756 µs) in front of or behind the reference (which is fed to the GDK card via the rack...
- Page 17 The keyer card adds a slight delay to the outputs in comparison to the inputs. These are the measured delays per format: Format Measured delay 1080p Not measured 1080i 2 lines delay, ±11.89 µs 720p 3 lines delay, ±8.46 µs 1 line delay, ±23.9 µs Synapse GDK200 | 4. The GDK200 Card |...

Page 48: Appendix 3: Quad Speed Add-On Bus
Appendix 3: Quad Speed ADD-ON Bus Scope The internal audio ADD-ON bus needs an upgrade for certain applications. We want more channels (32 per video stream seems possible in the near future). And we want the bus to be bidirectional, i.e. 32 channels in and 32 channels out at the same time. - Page 49 Cascading of Quad Speed cards works identically to normal add-on cards. Every connection in the example below transports 16 mono audio channels (= 32 channels per color). It shows the inter-slot connections ‘in quad Speed mode’ as part of the frame bus PCB. Synapse GDK200 | Appendix 3: Quad Speed ADD-ON Bus |...
- Page 50 The system makes use of the same passive copper traces on the internal bus PCB as normal add-on bus cards. The maximum amount of ADD-ON cards in Quad Speed mode is 3. These 3 ADD-ON cards will run all on the same clock in the same phase as the MASTER-CARD.
