Security Link Over Coax SLOC Transmitter TW3801 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. • Single-channel SLOC transmitter modem • Embedded SLOC camera modem • Simultaneous transmission of IP video data and analog CVBS video over up to 500m of RG59 coaxial cable • Analog CVBS video preview support • Proprietary adaptive analog equalizer for extending the reach of CVBS video • Proprietary SLOC-based IP DVR detection • Creates a full-duplex 100BASE-T digital link • 36Mbps downlink speed from TW3801 to TW3811 • 4Mbps uplink for SLOC compliance • Ethernet MAC MII/RMII interface for interfacing to Camera ISPs • Ethernet PHY MII/RMII interface for interfacing to Ethernet PHY chip • I2C 2-wire control interface • Integrated PLL with 25MHz crystal interface • 1.8V, 3.3V supplies • 100-TQFP 12mmx12mm Package Application Block Diagram IP Camera Analog CVBS Ethernet SLOC Adapter Module MCU optional 100BASE-T PHY TW3801 Up to 500m of RG59 cable One-Channel SLOC Receiver MCU optional TW3811 EL8101 100BASE-T PHY Analog CVBS Ethernet SPOT Monitor DVR Network Switch Simplified Application Schematic Ethernet I/O RJ45 IP Camera CVBS Input 1.8V 3.3V 3.3V MII or RMII PHY MII / RMII Interface VDD_D VDD_IO VDD_A COAX_IN 10µF CVBS_IN COAX_OUT
