LYNX YELLOBRIK SDI FRAME SYNCHRONISER AND SCALER/UP/DOWN/CROSS CONVERTER - 3Gbit - PVD 1800
The PVD 1800 is a 'compact, broadcast quality, SDI frame synchroniser and scaler/up/down/cross (UDX) converter for professional applications in broadcast, post production, pro a/v, industrial, commercial, educational and medical environments'. It features 'multi-format support, with auto detection, of SDI formats up to 3Gbit/s as standard on BNC coaxial cable and has the capacity for an optional SFP fibre optic in/output'.
The module can be configured to auto-detect an electrical or optical input and can automatically switch between them if signal loss is detected. Input changeover can also be triggered manually or automatically (by LYNX APPolo Control or a third-party control system) using the GPI input. Any input (coaxial or fibre) is automatically routed to both coaxial and fibre outputs, provided a fibre TX (transmitter) or TR (transceiver) SFP is fitted. Video processing utilises a 'cross lock' compatible reference input with robust 'flywheel' synchronisation that will accommodate a wide variety of low-quality, asynchronous SDI sources and locks to the last provided reference signal if the external synchronisation is lost or intermittent.
The PVD 1800 includes an integrated broadcast quality Scaler/Up/Down/Cross Converter that converts between 3G, HD and SD formats. A selectable fast scale mode will deactivate the frame synchronizer and can reduce the processing delay to less than 10 lines. In addition, the converter can be automated by the incoming format description of the SDI (AFD, WSS or VI). In addition, the converter has a powerful Region of Interest (ROI) scaler that allows the user to extract a specific region of the incoming video and output this as a full format SDI output.
YelloGUI software application for Yellobriks
Many of the PVD 1800 frame synchroniser settings can be configured via DIP switches and the delay can be set using on-screen menus via the rotary / push encoder on the module. Additionally the yelloGUI software application provides graphical, on-screen setting of all parameters and enhanced information. A virtual image of the module is displayed, showing controls and status information. The internal signal-flow is displayed graphically and changes dynamically when a setting is changed. YelloGUI is available for PC or MAC OS and connection is via USB. YelloGUI can be downloaded free of charge (and run in device simulation mode without a yellobrik connected) from:http://www.lynx-technik.com/en/support/download-area/yellogui/
Firmware updates are always provided free of charge by Lynx Technik and can be downloaded from http://www.lynx-technik.com/en/support/download-area/yellobrik-firmware/ or by connecting the registered yellowbrik to a web connected PC or MAC and following the ‘update’ instructions.
Cross-lock and frame-rate conversion
The PVD 1800 frame synchronizer is fully 'cross-lock' compatible, meaning it can cross-lock between different standards. With a specific reference signal connected the synchronizer will drop or add frames to achieve a correctly synchronized (frame-rate converted) SDI output. During all conversions precise audio video timing is preserved and is free from 'pop and click' disturbances even when dropping or adding frames.
Note. This conversion simply drops and adds frames to achieve the desired output frame rate and will not provide the performance typical of a costly sophisticated standards converter.
Details of the conversion possibilities may be found in the Product resources.

Please see Lynx Yellobrik Power Supplies And Mounting Accessories.
Fibre SFP Modules
The transmitters provide an SDI output over fibre. The 'transceivers' can receive one SDI signal from one fibre and transmit an SDI signal over a second fibre simultaneously. The receivers enable the module to receive a fibre optic input signal.
Note (1): Maximum at 3Gbit/s.
In addition to those listed above, a range of CWDM fibre SFP modules may also be fitted where multiplexing or transmission distances up to 40km or 80km are required, please contact Technical Support for further information.
