The LMH6574 is a high performance analog multiplexer optimized for professional grade video and other high fidelity high bandwidth analog applications. It provides a 400 MHz bandwidth and supports multimedia and high definition television (HDTV) applications. The LMH6574 supports composite video applications with 0.02% and 0.05˚ differential gain and phase errors while driving a single, back terminated 75Ω load. It also has an 80 mA linear output current for driving multiple video load applications.
The LMH6574 is a high-performance analog multiplexer optimized for professional-grade video and other high-fidelity high-bandwidth analog applications. It features an output amplifier that selects any one of four buffered input signals based on the state of two address bits, providing a 400 MHz bandwidth at 2 Vp output signal levels.
