Converter board for analog AHD, HD-TVI and CVBS video to HD/SD-SDI output
The BlueBird Analog – SDI Adapter is a compact interface solution from Active Silicon’s BlueBird series of video adapters. It converts 75Ω single-ended or 100Ω differential analog (AHD/HD-TVI/CVBS) video signals into a low latency HD/SD-SDI output.
Selection of the active input is made at power-up by external signals or by VISCA command. The SDI output has the same resolution and frequency as the analog input signal. A 3.3V TTL serial channel is used to support VISCA commands for selecting the active input and communicating adapter board status to a host system.
A U.FL connector is used for the SDI output and a board-to-board multi-way connector is used for the power, TTL serial, three analog video inputs and the configuration signals for selection of the start-up input channel.
General information
| Status LED (“LED1”) | This LED illuminates when the BlueBird Analog – SDI Adapter is powered, the LED indicates the status of the adapter.
The LED function can be disabled using the VISCA adapter control command. |
| SDI Video Input/Output Mode | On power-up, reset or change of selected video input channel, the mode of the incoming video will be detected and converted to an equivalent SDI output. The video is not rescaled. AHD/HD-TVI 1080p30 [resolution: 1920×1080, frequency: 30 Hz, output: HD-SDI (1080p30)] |
| Video Input Channel Selection | The adapter board has two configuration input signals on the J1 multi-way connector. These are 3.3V CMOS level inputs with weak pullups to 3.3V; it is recommended that the configuration inputs are actively driven to 0V or 3.3V as required. When the adapter powers up, or the system is reset, the configuration inputs are read and the appropriate video channel selected (see table 2 in the datasheet). Selection of the video input channel can also be made using a VISCA command (this will override the initial selection made by the configuration inputs). For more information see the section on BlueBird Analog – SDI Adapter datasheet. |
| Test Pattern | A video test pattern output can be enabled on power-up/reset by setting the configuration input signals or (at any time) by sending the appropriate VISCA command over the serial communications channel. When set using the VISCA command the test pattern will use the same video mode as the currently selected video input channel, provided there is a valid signal present. For more information see the section on BlueBird Analog – SDI Adapter datasheet. |
| BlueBird Analog - SDI Adapter VISCA Commands | The VISCA protocol can support connection of up to 8 cameras/devices in a network; each camera is The default device address is normally 81. To differentiate adapter specific commands from other VISCA device commands, the adapter is pre-assigned a fixed VISCA address of 83. For more information see the section on BlueBird Analog – SDI Adapter datasheet. |
| BlueBird Analog – SDI Evaluation Board | The BlueBird Analog – SDI Evaluation board (AS-AP31C02-001-A) has been designed to enable fast and effective evaluation of the BlueBird Analog – SDI Adapter. The adapter board plugs directly into the BlueBird Analog – SDI Evaluation Board. The evaluation board supplies power and gives easy access to all the signals on the adapter board mezzanine connector (J1). The evaluation board carries two BNC connectors (J104, J103) for single ended analog video input. A three-way connector (J105, input 3) is for differential video input. An external AHD balun (commercially available) can be used to convert a single ended 75Ω signal into a 100Ω differential signal suitable for video input 3. A pair of DIP switches on the evaluation board enable selection of the video input channel to be used. The switch settings are only detected on power-up and cannot be used to change the input channel during operation. A USB_UART module enables an easy connection to the adapter serial communications for VISCA control of the adapter. The same module can be used for JTAG programming. The board also carries a U.FL socket that connects to a standard BNC connector for easy access to the adapter SDI output.

Connector specifications
| Mezzanine Connector: 20-way (J1) | The BlueBird Analog – SDI Adapter interfaces to external systems via a 20-way, 2mm height, hermaphroditic board to board mezzanine connector. Mating connectors can have heights of 2mm, 2.5mm or 3.5mm giving mated stack height options of 4mm, 4.5mm, 5.5mm (board-to-board distance). Connection direction in the following tables is with reference to the adapter, i.e. connections labelled input are an input to the adapter, outputs are outputs from the adapter (to the mated carrier board). Connector type: |
| SDI Output (J2) | The adapter board is fitted with a Hirose U.FL Micro Coaxial Connector (50 Ohm). Connector type: Solid Red: |
