Product number: TL6636-EVK

The TL6636 USB 3.0 interface board with trigger functionality from AIVION is tiny and easy to use HDTV USB3.0 video capture interface for the block cameras. The module receives digital video signals and sends UVC (USB Videl Class) compliant data packets to a connected host computer. Our compact TL6636 module enables the design of small camera systems that need only a single connection between the camera and PC. Video stream, control data and power will be connected by a USB 3.0 cable. For camera blocks that need more than 900 mA during startup, a Y-cable is required.

TL6636 PCB Outline


Camera Power

Camera supply voltage is generated on TL6636 by a boost converter circuit. This circuit provides 9.55V DC (+/-3%) to the camera.


USB3.0 is specified for 4.5W maximum output power per USB3.0 port on a computer. However, many main boards used in desktop computer systems are able to provide more USB3.0 output power. In case of notebook and laptop computers, IPCs and SBCs, it has to be checked case by case if USB3.0 output power is sufficient or not. This is in the sole responsibility of the user of TL6636. In case the host computer provides a USB3.1 port, it is recommended to use this one instead of a USB3.0 port.


TL6636 allows to use an external power supply in case USB3 power of the computer is not sufficient. As described on page 3 of this document, external power can be input on J7. Using a voltage of 6V DC is recommended. In case an external power supply is used, this voltage is used on TL6636 for the camera supply boost converter only. All other electronic devices on TL6636 are always powered from USB3 port. No adjustments on TL6636 are required for using external power. When powering up such a configuration, external power must be supplied before or coincident with USB3 power.


  • MP2030M-GS: Recommended, should be used
  • MP1010M-VC: Not required but can be used
  • MP1110M-VC: Not required but can be used

Host (PC) - Device Communication

TL6636 operates always as USB device which sends UVC compliant video data to a host PC. The host also communicates with the TL6636 via a serial communication channel (USB UART).

Connecting the TL6636 to the Host PC

Operating System Support

TL6636 can be used with operating systems which fully support USB UVC type data and communication. Currently supported Microsoft Windows operating systems:

  • Windows 7 (32 and 64bit)
  • Windows 8.1 (32 and 64bit)
  • Windows 10 (64bit, version 1511)

Driver Requirements

Full UVC compliant driver is required. Such drivers are supplied with Microsoft Windows 7 and 8 . Manual driver installation is not necessary. For the USB UART feature, the class driver is used. Aivion provides suitable driver assignment files. Win 10 does not require such a driver assignment file.

Video Application on Host PC

Video display and recording can be done with standard application programs like VLC player, Mplayer or similar. VLC and Mplayer are open source based applications and can be free downloaded. If users want to design their own applications software, they are free to do so. All software programming tasks are OS based and have to be built upon UVC drivers. For further information please refer to Microsoft Windows API information.

Controlling TL6636 from the Host PC via USB UART

TL6636 supports the USB UART functionality. FCB cameras connected to TL6636 can be controlled via a virtual COM port. Any host software which uses COM ports can be used. The USB UART channel is transparent for any protocol. Communication speed is 9600bit/ s or 38400bit/s maximum. Other COM port settings are (8N1).

Real-Time external Trigger Operation


Tamron’s MP2030M-GS global shutter block camera module allows for real- time triggered still image capture. Refer to MP2030M-GS technical manual provided by Tamron for details on real-time triggered still image capture operation. TL6636 USB3 full HD video streamer provides a trigger mode input for selecting one out of two available trigger modes.

Mode 1 (default, pin2/J9 0V or open): External direct trigger

Trigger pulse input on pin1/J9 is glitch filtered and driven to MP2030M-GS trigger input po

Mode 2 (pin2/J9 3.3V): Automatic periodic trigger (demo mode)

After selecting and activating trigger mode at MP2030M-GS by the related VISCA commands, the automatic trigger period is set to 1.5s. In this demo mode the camera takes an image every 1.5s (approx.).
