AD8194 is a 2 input 1 output HDMI/DVI high speed signal switch with pin-to-pin compatibility with the AD8193. It enables HDMI 1.3-compliant receiver and supports data rates of 250 Mbps to 2.25 Gbps and pixel clocks of 25 MHz to 225 MHz. AD8194 provides fully buffered unidirectional inputs/outputs. Its equalized inputs can operate with long HDMI cables (20 m at 2.25 Gbps). AD8194 features matched 50 Ohm input and output on-chip terminations, low added jitter, single-supply operation (3.3 V), and is RoHS-compliant LFCSP.
The AD8194 is a low‑cost quad 2:1 TMDS switch designed for high‑speed HDMI/DVI video applications. It provides fully buffered, equalized inputs and a single output, supporting data rates up to 2.25 Gbps and operating over a –40 °C to +85 °C temperature range.
Key features include 2 inputs and 1 output, single‑supply 3.3 V operation, matched 50 Ω terminations, low added jitter, and an exposed heat slug for improved thermal performance. The device is supplied in a 32‑lead LFCSP package and is RoHS‑compliant, making it suitable for HDTV sets, projectors, A/V receivers, and set‑top boxes.
