NA1012B-ET | HDMI TO 3G/HD-SDI CONVERTER (board to board connector)
The NanoConverter NA1012B-ET from AIVION 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 the highest priority. For this purpose, HDMI input video and 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. SDI video output is available on two right-angled MCX coaxial connectors. Features One HDMI input HDMI input over board to board connector. Compliant to HDMI 1.4a and DVI 1.0.Input format support: RGB 444 YCbCr 444 YCbCr 422 Two SDI outputs 75 ohm MCX jacks connector. Supporting bit rates due to SMPTE292M and SMPTE424M 1.485 Gbps 1.485/1.001 Gbps 2.97 Gbps 2.97/1.001 Gbps Full-HD Support Supported Video formats: 1080p at 50/25/24/59.94/29.97/23.98/60/30 1080i at 50/59.94/60 720p at 50/ 59.94/60 Extendet Temperature Range -40°C/+85°C = -40°F/185°F Humidity: 20% - 80% Small form factor PCB dimensions 38mm x 38mm Native video signal processing No image scaling, no format conversion.

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 The current device version does not support audio. NA1012B-ET does not process HDCP encrypted HDMI input signals. 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. 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), NA1012B-ET Heat Sink EK-PA1131 For test and evaluation purposes adaptor EK-PA-1131 is available. It provides a HDMI A-type connector for video input as well as USB2 connector which can be used to supply 5V DC power to NA1012B-ET. In addition it allows easy access to the debug/status port by an USB2 UART.
