Security Link Over Coax™ (SLOC™) Transmitter

SLOC™ (Security Link Over Coax) is a transmission protocol for simultaneously transmitting analog CVBS video and digital IP video over a single coaxial cable. The TW3801 is the transmitting (“camera”) end of a SLOC link, combining Ethernet digital video data and analog CVBS video into a single SLOC signal that can be transmitted over 500m of coaxial cable. It can be embedded into a camera or configured as a stand-alone IP+CVBS-to-SLOC converter. The TW3801 includes an AFE, digital modem, and two Ethernet MII/RMII interfaces. The device accepts an analog CVBS signal and an Ethernet (R)MII signal and encodes it into a SLOC signal.
