GENERAL DESCRIPTION
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.
