  • Single board with both 50 Ω and 75 Ω termination
  • ±5 V operation

Product Details

The ADV3221 and ADV3222 are high speed, high slew rate, buffered, 4:1 analog multiplexers. They offer a −3 dB signal bandwidth greater than 800 MHz and channel switch times of less than 20 ns with 1% settling. With lower than −58 dB of crosstalk and −67 dB isolation (at 100 MHz), the ADV3221 and ADV3222 are useful in many high speed applications. The differential gain error of less than 0.02% and differential phase error of less than 0.02°, together with 0.1 dB gain flatness out to 100 MHz while driving a 75 Ω back terminated load, make the ADV3221 and ADV3222 ideal for all types of signal switching.


The ADV3221/ADV3222 include an output buffer that can be placed into a high impedance state, which allows multiple outputs to be connected together for cascading stages without the off channels loading the output bus. The ADV3221 has a gain of +1, and the ADV3222 has a gain of +2; both devices operate on ±5 V supplies while consuming less than 7.5 mA of idle current. The channel switching is performed via latched control lines, allowing synchronous updating in a multiple ADV3221/ADV3222 environment. The ADV3221/ADV3222 are offered in a 16-lead SOIC package and are available over the extended industrial temperature range of −40°C to +85°C. 


This user guide provides all of the supporting documentation for working with the ADV3221-EVALZ/ADV3222-EVALZ evaluation board. Additional information is available in the ADV3221/ADV3222 data sheet, which should be consulted in conjunction with this user guide when working with the evaluation board.
