AVerMedia CN312MN M.2 HDMI and SDI Frame Grabber with 2K60 Inputs

Medical carts, labs and indoor vision systems often have to capture an SDI camera and an HDMI source in a small embedded PC with only an M.2 slot to spare. The AVerMedia CN312MN takes both on one M.2 2280 card: one HDMI 1.4a input and one 2K SDI input, handled as two capture channels. It is the standard-temperature build; the CN312MW is rated -20 °C to 70 °C with airflow, and the CN312MC adds conformal coating to that wide-temperature design.

The SDI input accepts up to 2048 x 1080 at 60 fps and the HDMI input up to 1920 x 1200 at 60 fps, with recording at 1920 x 1080 and 60 fps. Driver output is 8-bit in NV12, I420, YV12, YUY2, YUYV, UYVY, IYU2, BGR24 or BGR32, and 10-bit input signals are accepted. Audio is embedded on both inputs at 32, 44.1 or 48 kHz.

The CN312MN connects over PCIe Gen2 x2 in an M.2 2280 Key M slot and draws 3.3 W. The package includes a BNC cable and an HDMI micro coaxial cable. Multi-card operation is supported, and AVerMedia provides Windows drivers and Linux V4L2 drivers for x86 and x64 hosts. For a single HDMI source at up to 4K30, the CN311-H uses the same M.2 format.

The CN312MN is rated from 0 °C to 40 °C in operation and -40 °C to 85 °C in storage, at 0% to 95% RH, with FCC and CE marks. We supply the CN312MN fitted and tested in the host computer it will run in, with cables routed, drivers installed and both inputs checked before it ships. Where the host will see heat or cold beyond that range, the wide-temperature builds are usually the better fit.
