Yuan SC5A0N2-L SDI PCIe SDI Capture Card with 2 x SDI Inputs and 1080p30 Capture
PCI ExpressSC5A0N2-L SDI Overview
Two-camera recording is the everyday case for SDI capture: a wide shot and a close-up in a lecture hall, or two angles on a test or production line. The SC5A0N2-L SDI is Yuan’s two-channel PCIe SDI capture card for it, taking two SDI feeds into one x1 slot and compressing both on the card with an H.26X encoder.
Each input accepts 1920 x 1080p at 60/50 fps and captures at 30/25 fps. HD-SDI sources run at 1080p30/25/24, 1080i60/50 and 720p60/50, and SD-SDI at 720 x 480i60 and 720 x 576i50. It delivers RGB24 and RGB32 at 4:4:4, YUY2 at 4:2:2 and YV12 or NV12 at 4:2:0, which lets software pick the format its encoder or vision library expects. Each channel captures stereo embedded audio at 16-bit and 32 to 48 kHz.
The card uses a PCIe x1 Gen2 slot and supports multiple instances and multiple cards per host, with cropping and scaling, automatic signal detection and deinterlacing on board, plus 16 GPIO and a watchdog. Yuan supplies a Windows and Linux SDK for custom applications, and DirectShow and V4L2 compatibility means tools such as OBS, vMix, Cisco Webex and Zoom can open the card directly. The SC5C0N2-L SDI is the two-channel SDI capture card at 1080p60, and the SC5A0N4 SDI takes four SDI feeds on PCIe x4.
Drivers cover Windows 7 to Windows 10, Linux 2.6.14 or higher in 32-bit and 64-bit form, Linux on ARM and the NVIDIA Jetson TX2, Nano, AGX Xavier and Xavier NX. So a two-camera recorder can be built on Windows, Linux or a Jetson module with the same card. The board measures 122.3 x 68.9 mm.

Official Yuan USA Distributor
Things Embedded is an official Yuan USA distributor, supplying the SC5A0N2-L SDI configured for USA broadcast and education projects. Within the Yuan range the SC5C0N2-L SDI records two SDI channels at 1080p60, and the SC5A0N4 SDI brings four SDI inputs to a PCIe x4 slot.
As a two-channel SDI recorder the SC5A0N2-L SDI sits among our SDI capture cards and our PCIe capture cards. Where two SDI cameras must be recorded at 1080p30 from one x1 slot, this is the model to specify.
