MAX4121 - Maxim

MAX4121 330MHz Buffered Video Switches/ Crosspoint Building Blocks

The MAX4111/MAX4121/MAX4221 wideband video switches are optimized for high-definition, broadcastquality, composite (HDTV, NTSC, PAL, SECAM, and RGB) video switching arrays. Their open-loop buffer amplifiers offer 0.1dB gain flatness to 150MHz. They operate from ±5V supplies and feature differential phase and gain error of only 0.01°/0.01%, respectively. The .
