GENERAL DESCRIPTION The ADV3205 is a fully buffered crosspoint switch matrix that The ADV3205 includes 16 independent output buffers that can operates on 5 V, making it ideal for video applications. It offers be placed into a disabled state for paralleling crosspoint outputs. a 3 dB signal bandwidth of 60 MHz and channel switch times of The ADV3205 has a gain of +2 and operates on voltage supplies less than 60 ns with 0.1% settling. The ADV3205 has excellent of 5 V while consuming only 34 mA of current. Channel crosstalk performance, and ground/power pins surround all inputs switching is performed via a serial digital control (which can and outputs to provide extra shielding required for the most accommodate daisy-chaining of several devices) or via a parallel demanding applications. The differential gain and differential control, allowing updating of an individual output without phase of better than 0.1% and 0.1, respectively, along with 0.1 dB reprogramming the entire array. flatness out to 10 MHz, make the ADV3205 an excellent choice The ADV3205 is packaged in a 100-lead LQFP and is available for many video applications. over the commercial temperature range of 0C to 70C.
