The ADV3219/ADV3220 are ADI company's 2:1 analog multiplexers. Its main features are excellent ac performance, low power consumption and high video performance. Applications include video, compressed video, 3-level digital video and data communication.
The ADV3219 and ADV3220 are high‑speed, buffered 2:1 analog multiplexers designed for routing video, data communications and telecommunications signals. They provide a –3 dB bandwidth greater than 800 MHz, selectable gain (+1 for ADV3219, +2 for ADV3220), and very low crosstalk (‑82 dB @ 5 MHz, ‑60 dB @ 100 MHz). The devices include an output buffer that can be placed in a high‑impedance state for cascading multiple outputs.
The handbook lists detailed electrical specifications, absolute maximum ratings, thermal resistance, power dissipation limits, pin configurations, and typical performance characteristics. It also includes application examples such as NTSC/PAL video routing and high‑speed data communications, along with mechanical dimensions and ordering information.
