Analog Devices AD8197BASTZ 4:1 HDMI/DVI TMDS Switch with Equalization 100‑LQFP

The Analog Devices AD8197BASTZ is a high‑performance HDMI/DVI switch IC designed for video systems requiring robust signal routing and integrity over long cable runs. It supports HDMI 1.3/DVI standards with equalized TMDS inputs and pre‑emphasized TMDS outputs, enabling reliable high‑speed switching at data rates up to 2.25 Gbps and pixel clocks from 25 MHz to 225 MHz. The device can be configured as a single 4:1 HDMI/DVI link switch or multi‑channel switch with flexible signal bundling options. Integrated I²C and parallel control interfaces provide flexible system control, while on‑chip 50 Ω termination and selectable output impedance help optimize signal integrity. Encased in a 100‑lead LQFP (14×14 mm) package, this IC operates from a 3.0 V to 3.6 V supply and is suitable for advanced video products such as HDTVs, set‑top boxes, displays, and projectors.
