ADV3221 is a pin-for-pin upgrade to the HA4344

Gain = +1 (ADV3221) or gain = +2 (ADV3222)

Low all hostile crosstalk of −85 dB @ 5 MHz, and

−58 dB @ 100 MHz

Latched control lines for synchronous switching

High impedance output disable allows connection of

multiple devices without loading the output bus

16-lead SOIC

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

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.

TheADV3221 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 Ω back terminated load, make the ADV3221

and ADV3222 ideal for all types of signal switching.

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.

The ADV3221/ADV3222 include an output buffer that can be

placed into a high impedance state. This allows multiple outputs
