AIVION NA1012B-ET

The AIVION NA1012B-ET is a very small form factor HDMI to SDI converter module. It is designed for applications where minimum size and a wide operating temperature range have highest priority. For this purpose HDMI input video as well as power supply voltage are supplied over a board2board connector eliminating the need for HDMI and power cables. The converter module can be easily plugged onto system boards having a mating board2board connector available.

Notes NA1012B-ET

  1. NA1012B-ET converts video signals received from a DVI or HDMI source for transmission over an 3G/HD-SDI interface which requires clock signals to be in a well defined range. This might not be the case when standard HDMI or DVI output of desktop computers, laptop computers ot other consumer devices are used as signal source.
    The HDMI/DVI TMDS input clock requirements are:
    • 3G mode: 148.5MHz or 148.5 MHz/1.001 +/- 60ppm
    • HG mode: 74.25MHz or 74.25MHz/1.001 +/- 80 ppm
  2. The current device version does not support audio.
  3. NA1012B-ET does not process HDCP encrypted HDMI input signals.
  4. The device detects and measures video input parameter and adjusts all necessary settings accordingly. Manual control is not required. However, the serial control interface can be used for status checking. Terminal software like TeraTerm can be used, whereas parameters have to be set to 38400bps, 8 data bits, no parity and 1 stop bit (8N1). No handshake must be used.
  5. Depending on the system configuration and thermal as well as mechanical design of the system board, a heat sink might be required. In such a case the heat sink or heat pipe should contact to one of the devices marked with a yellow square (see images below),
