Description

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 diffe-rential 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 ? 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. This 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; they both 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 envi-ronment.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.Applications Routing of high speed signals including ? ? Video (NTSC, PAL, S, SECAM, YUV, RGB) ? ? Compressed video (MPEG, wavelet) ? ? 3-level digital video (HDB3) ? ? Data communications ? ? Telecommunications
