TW3811-TC1-CRT Renesas

+ + Security Link Over Coax (SLOC) Receiver TW3811 Features SLOC (Security Link Over Coax) is a transmission protocol for Simultaneous transmission of IP video data and analog simultaneously transmitting analog CVBS video and digital IP CVBS video over up to 500m of RG59 coaxial cable video over a single coaxial cable. Analog CVBS video preview support The TW3811 is the receiving end of a SLOC link, converting the Proprietary adaptive analog equalizer for extending the single SLOC signal on the coaxial cable back to separate reach of CVBS video Ethernet digital video data and analog CVBS video. It can be Proprietary SLOC-based IP camera detection embedded into a DVR to enable one or more SLOC inputs or Creates a full-duplex 100BASE-T digital link configured as a stand-alone SLOC-to-IP+CVBS converter. 36Mbps downlink speed from TW3801 to TW3811 The TW3811 includes an AFE, digital modem, and two 4Mbps uplink for SLOC compliance Ethernet MII/RMII interfaces. The device accepts a SLOC Ethernet MAC MII/RMII interface for interfacing to DVR/NVR output signal from a SLOC transmitter and decodes it into an network processor SoC analog CVBS signal and an Ethernet MII signal.
