| Security Link Over Coax SLOC Receiver TW3811 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 TW3811 is the receiving end of a SLOC link, converting the single SLOC signal on the coaxial cable back to separate Ethernet digital video data and analog CVBS video. It can be embedded into a DVR to enable one or more SLOC inputs or configured as a stand-alone SLOC-to-IP+CVBS converter. The TW3811 includes an AFE, digital modem, and two Ethernet MII/RMII interfaces. The device accepts a SLOC output signal from a SLOC transmitter and decodes it into an analog CVBS signal and an Ethernet MII signal. • Single-Channel SLOC receiver modem • Multi-Channel SLOC receiver modem • Embedded DVR • 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 camera 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 DVR/NVR network processor SoC • Optional Ethernet PHY MII/RMII interface for interfacing to external Ethernet PHY chip • I2C 2-wire control interface • Integrated PLL with 25MHz crystal interface • 1.8V, 3.3V supplies • 100-TQFP 12x12mm 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 SLOC Coax I/O 22µF 0.1µF 470µF 75 150nH XTAL_IN XTAL_OUT SCL SDA 3.3V 3.3V 1.8V VDD_A VDD_IO COAX_IN VDD_D |
