LMH6570MA

TEXAS INSTRUMENTS  LMH6570MA  芯片, 高速多路复用器 2:1

The is a 2:1 high speed Video Multiplexer optimized for professional grade video and other high fidelity, high bandwidth analogue applications. The output amplifier selects one of two buffered input signals based on the state of the SEL pin. The LMH6570 provides a 400MHz bandwidth at 2VPP output signal levels. Multimedia and high definition television HDTV applications can benefit from the 0.1dB bandwidth of 150MHz and the 2200V/µs slew rate of multiplexer. This multiplexer supports composite video application with its 0.02% and 0.05° differential gain and phase errors for NTSC and PAL video signals while driving a single, back terminated 75R load. An 80mA linear output current is available for driving multiple video load applications. The multiplexer gain is set by external feedback and gain set resistors for maximum flexibility.
