ADI introduce industry minimum encapsulated 3 differentiating line drive unit
AD8133 of ADI the intersection of industry and minimum encapsulated three the intersection of differentiating and line drive unit at present, it become get one 4 mm in the chip of * 4 mm three the intersection of differentiating and the intersection of line drive unit and complete works. As the engineer uses this new device to drive on a twisted pair cable transmissive and red and turquoise (RGB) Can eliminate three the intersection of chip and solution at the three signal, thus make cost cut down 50% and enable printed circuit board (PCB) Area reduce 75%. As to setting up outside the computer, long-range display unit and keyboard display mouse (KVM) Application, than use discrete three operation amplifier drive the intersection of twisted pair cable and transmissive solution of video signal, RGB of differentiating, have very loud to progress AD8133. The one most key to the application is to enable the electromagnetic disturbance of radiation (EMI) Minimize. AD8133 outputs the gain to noise temperature ratio and - 60 dB in 50 MHz place phase place balance error to has unique internal common modes that is feedbacked and offered, inhibit EMI radiation and can use 5 kinds of unshield twisted pairs (UTP) Cable. A lot of employ the cost that benefit from the twisted pair cable solution to be lower than the coaxial solution. AD8133 driver accepts single-end is input and offered the differentiating to export; Among them every amplifier has a stationary gain to noise temperature ratio of 2 times to compensate the decay that the resistor of the line terminal cause. Though AD8133 specially designs to drive the RGB signal, it can be used for driving any type of analog signal or high speed data transmission. This device drives 5 kinds of UTP cables or differentiating PCB to transmit collinear ability in order to the lowest signal attenuation. Last state the AD8133 one output in order to in circuit isolate and employ with cooperating and using while connecting by dioding in series, thus it is apt to realize the multiplexing of differentiating to allow on the same kind of twisted pair cable. AD8133 driver can use together with AD8129 and AD8130 differentiating receiver. AD8133 adopts XFCB bipolar technology of new generation of ADI Company to make, it has 225 MHz large signal bandwidth and 1600 V / μ s conversion rate. It outputs voltage amplitude of common mode and can be adjusted through exerting one voltage to Vocm can input the pin convenientlying. This Vocm pin can be used for sending the signal superposed in the common mode voltage output too. Stock and offering AD8133 a thousand sheets of ordering amount offered as 2.59 dollar each and can offer the batch products now. Work this device in -40 ℃+85 ℃industry temperature range and if you can't last products, adopt 24 pin LFCSP not to be capsulated at present.
