Nov 29, 2012 Security Link Over Coax (SLOC) Receiver Features SLOCв„ў (Security Link Over Coax) is a transmission protocol for
simultaneously transmitting analog CVBS video and digital IP
video over a single coaxial cable. Simultaneous transmission of IP video data and analog
CVBS video over up to 500m of RG59 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. 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 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. 36Mbps downlink speed from TW3801 to TW3811 4Mbps uplink for SLOC compliance Ethernet MAC MII/RMII interface for interfacing to DVR/NVR
