Ultra HDMI (1.4b) interface for 4K block cameras
TL4K1152
The TL4K1152 is a digital serial UHD HDMI interface, with a small form factor, optimal for 4K block cameras. It is connected to the digital video interface (LVDS) of the block camera. Camera video input signals are equalized, processed and output via an HDMI (3.4Gbps HDMI1.4b) port. Camera control is via a transparent full-duplex communication channel. The physical interface between the block camera and camera controller/uC/PC is based on the RS232 level or 3.3V TTL level.
