GENERAL DESCRIPTION

The ADV3221 and ADV3222
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
ADV3222 are useful in many high speed applications. The
