The ADV3202/ADV3203 is a 300 MHz, 32×16 buffered analog crosspoint switch from Analog Devices. The product is available in G = +1 (ADV3202) or G = +2 (ADV3203) operation modes, with a single supply of +5 V, dual supplies of ±2.5 V or ±3.3 V (G = +2), and support for serial programming of the switch array and a 2:1 OSD insertion mux per output. The product also features a high impedance output disable function to allow connection of multiple devices while minimizing the output bus load. In addition, the product offers excellent video performance (60 MHz 0.1 dB gain flatness, 0.1% differential gain error, and 0.1° differential phase error), and excellent AC performance (bandwidth > 300 MHz, slew rate > 400 V/μs, power consumption 1 W, and low all hostile crosstalk -48 dB @ 5 MHz).
The ADV3202 and ADV3203 are 32 × 16 analog crosspoint switch matrices designed for high‑speed video routing, CCTV, and video‑conferencing applications. They feature selectable sync‑tip clamp inputs, on‑screen‑display (OSD) insertion multiplexing, and low‑crosstalk performance.
Key specifications include a bandwidth greater than 300 MHz, slew rate over 400 V/µs, supply options of +5 V, dual +2.5 V or dual +3.3 V, and operation over an industrial temperature range of –40 °C to +85 °C. Detailed pin‑out tables, timing diagrams, and absolute maximum ratings are provided for design integration.
