Outline
CS7211 DVB-T transmitter is used for digital TV terrestrialwireless transmitting system. It can work with COFDM modulator,transmitted digital channels to the digital TV receiver fornot-long distance transmission with high broadcasting quality..
Features
??? Accord with DVB-T ETS300 744 standard.
??? Digital TV RF stream ASI serial connecter and SPI parallelconnecter
??? With whole solid-state circuit design, super-linearity,broad-band power amplifier unit and power amplifier modularizationdesign. Adopted LDMOS high-power tube with great redundancy, easyto install or maintain.
??? With over-voltage, over-current, over-heat and over-highstanding wave ratio protection, the equipment can worksecurely.
??? With digital/analogue compatible output band-pass filter,adopted high-power synthesis technology, with low insertion lossand high out-of-band suppression.
??? Support SFN and MFN network.
??? Support ALC, AGC as different conditional.
??? Support compelled-wind cool design, with low powerconsumption and low noise.
??? Al-alloy cover designed, rain-proof, damp-proof.
??? Remote control, GSM alarm, optional.
