PRODUCT DESCRIPTIONThe AD8110 and AD8111 are high-speed 16 × 8 video crosspointswitch matrices. They offer a –3 dB signal bandwidthgreater than 260 MHz, and channel switch TImes of less than25 ns with 1% settling. With –78 dB of crosstalk and –97 dBisolaTIon (@ 5 MHz), the AD8110/AD8111 are useful in manyhigh-speed applicaTIons. The differential gain and differentialphase of better than 0.02% and 0.02° respectively, along with0.1 dB flatness out to 60 MHz, make the AD8110/AD8111ideal for video signal switching.The AD8110 and AD8111 include eight independent outputbuffers that can be placed into a high impedance state for parallelingcrosspoint outputs so that off channels do not load theoutput bus. The AD8110 has a gain of +1, while the AD8111offers a gain of +2. They operate on voltage supplies of ±5 Vwhile consuming only 50 mA of idle current. The channelswitching is performed via a serial digital control (which canaccommodate “daisy chaining” of several devices) or via a parallelcontrol, allowing updating of an individual output without reprogrammingthe entire array.The AD8110/AD8111 is packaged in an 80-lead LQFP packageand is available over the extended industrial temperature rangeof –40°C to +85°C.
