DESCRIPTION The AD8146/AD8147/AD8148 are high speed triple, differential or single-ended input to differential output drivers. The AD8146 and AD8147 have a fixed gain of 2, and the AD8148 has a fixed gain of 4. They are all specifically designed for the highest resolution component video signals but can be used for any type of analog signals or high speed data transmission over either Category 5 UTP cable or differential printed circuit board (PCB) transmission lines. AD8145 triple differential-to-singled-ended receiver, and the AD8117 crosspoint switch to produce a video distribution system capable of supporting UXGA or 1080p signals. Manufactured on the Analog Devices, Inc. second generation XFCB bipolar process, the drivers have large signal bandwidths of 700 MHz and fast slew rates. They have an internal common-mode feedback feature that provides output amplitude and phase matching that is balanced to 60 dB at 50 MHz, suppressing even-order harmonics and minimizing radiated electro FEATURES Triple high speed fully differential driver 700 MHz, 3 dB, 2 V p-p bandwidth (AD8146/AD8148) 600 MHz, 3 dB, 2 V p-p bandwidth (AD8147) 200 MHz, 0.1 dB, 2 V p-p bandwidth 3000 V/ s slew rate Fixed gain (AD8146/AD8147: G = 2, AD8148: G = 4) Differential or single-ended input to differential output Can be used as differential-to-differential receiver Adjustable output common-mode voltage (AD8146) Internal common-mode feedback network Output balance error 50 dB @ 50 MHz On-chip, sync-on common-mode encoding (AD8147/AD8148) Output pull-down feature for line isolation Low power: 57 mA @ 5 V for 3 drivers (AD8146) Wide supply voltage range: +5 V to 5 V Available in a small 4 mm 4 mm LFCSP APPLICATIONS QXGA or 1080p video transmission KVM networking Video over unshielded twisted pair (UTP) Differential signal multiplexing FUNCTIONAL BLOCK DIAGRAMS AD8146OPD1VS-2-IN A3+IN A4VS-5VOCMCVS+-IN C+IN CVS-1817161514-OUT A6-OUT C13VS+-IN B+IN BVS-VOCMA2423222120VOCMB19+OUT AVS++OUT B-OUT BVS+7 Specifications subject to change without notic
