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