Dual 3 Gbps Ultra HD SDI interface for 4K block cameras
TL4K1161
The TL4K1161 is a small form factor serial digital video interface (SDI). It is connected to the digital video interface (LVDS) of the block camera. Camera video input signals are equalized, processed and output via coaxial connections. The Dual Link 3G-SDI output conforms to SMPTE ST425-3, 2si mapping, the FHD output conforms to SMPTE ST425-1 Level A standards. Camera control is via a transparent full-duplex communication channel. The physical interface between the camera and camera control / PC is based on RS232 or 3.3V TTL level.
