Detailed Description

CS7211 DVB-T Transmitter Outline CS7211 DVB-T transmitter is used for digital TV terrestrial wireless transmitting system. It can work with COFDM modulator, transmitted digital channels to the digital TV receiver for not-long distance transmission with high broadcasting quality.. Features ◎ Accord with DVB-T ETS300 744 standard. ◎ Digital TV RF stream ASI serial connecter and SPI parallel connecter ◎ With whole solid-state circuit design, super-linearity, broad-band power amplifier unit and power amplifier modularization design. Adopted LDMOS high-power tube with great redundancy, easy to install or maintain. ◎ With over-voltage, over-current, over-heat and over-high standing wave ratio protection, the equipment can work securely. ◎ With digital/analogue compatible output band-pass filter, adopted high-power synthesis technology, with low insertion loss and high out-of-band suppression. ◎ Support SFN and MFN network. ◎ Support ALC, AGC as different conditional. ◎ Support compelled-wind cool design, with low power consumption and low noise. ◎ Al-alloy cover designed, rain-proof, damp-proof. ◎ Remote control, GSM alarm, optional.
