HDMI to 3G/HD-SDI converter - extended temperature range
NA1012-ET
NA1012-ET is an HDMI to SDI converter module with a very small form factor It is designed for applications where minimal size and a wide operating temperature range are top priorities. SDI video output is available on two straight MCX coaxial connectors.
NA1012-ET converts video signals received from a DVI or HDMI source for transmission over a 3G/HD-SDI interface, which requires the clock signals to be within a well-defined range. This may not be the case when using the standard HDMI or DVI output of desktop computers, laptops, or other consumer devices as a signal source.

More information about NA1012-ET
- NA1012-ET converts video signals received from a DVI or HDMI source for transmission over a 3G/HD-SDI interface that requires clock signals in a well-defined range. This may not be the case when using the standard HDMI or DVI output of desktop computers, laptops, or other consumer devices as a signal source.
The HDMI/DVI TMDS input clock requirements are:
3G-Modus:
148.5MHz or 148.5 MHz/1,001 +/- 60ppm HD mode:
74,25MHz or 74,25MHz/1,001 +/- 80 ppm - The current device version does not support audio.
- NA1012-ET does not handle HDCP encrypted HDMI input signals.
- The device detects and measures the video input parameters and adjusts all necessary settings accordingly. Manual control is not required. However, the serial control interface can be used to check status. Terminal software such as TeraTerm can be used, with the parameters set to 38400bps, 8 data bits, no parity and 1 stop bit (8N1). No handshake may be used.
- Depending on the system configuration and the thermal and mechanical design of the system board, a heat sink may be required. In such a case, the heat sink or heat pipe should be connected to one of the devices marked with a yellow square.
