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 GENERAL 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 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.
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 th...
