| FHP3194 4:1 High-Speed Multiplexer October 2006 FHP3194 4:1 High-Speed Multiplexer • 0.1dB gain flatness to 90MHz 2Vpp • differential gain/phase error • 500MHz large signal -3dB bandwidth at G = 2 • 2200V/µs slew rate • 75mA output current easily drives two video loads • 70dB channel-to-channel isolation • 13mA supply current • 3.5mA supply current in disable mode • 2.5mA supply current in shutdown mode • Fully specified at ±5V supplies • Lead-free SOIC-14 and TSSOP-14 packages • Video switchers and routers • Multiple input HDTV switching • Picture-in-picture video switch • Multi-channel ADC driver The FHP3194 is a 4:1 analog multiplexer designed for high-speed video applications. The output amplifier is a high-speed current feedback amplifier that offers stellar large signal performance of 500MHz -3dB bandwidth and 90MHz 0.1dB bandwidth. The gain of the output amplifier is selectable through two external resistors Rf and Rg , allowing further design flexibility. The 2Vpp bandwidth performance and 2200V/us slew rate exceed the requirements of high-definition television HDTV and other multimedia applications. The output amplifier also provides ample output current to drive multiple video loads. Two address bits A0 and A1 are used to select one of the four inputs. The FHP3194 offers better than 70dB channel isolation. The FHP3194 offers both shutdown and disable capability. During shutdown, the FHP3194 consumes only 2.5mA of supply current. During disable mode, only the output amplifier is disabled, reducing output glitches and allowing for multiplexer expansion.
