Description

ProTek Analog’s PAUSB42 is a bidirectional two-port Hi-speed USB2.0 switch. Configured as a double-pole double throw (DPDT) switch, it is optimized for swit ching between two 480Mbps sources or a Hi-speed and Full-speed 12Mbps source. The bandwidth of 895MHz a llows passing of the 3 rd Harmonic, resulting in minimal edge and phase distortion. Superior channel to channel crosstalk minimizes interference. The PAUSB42 contains circuitry for Power-Off protection when V CC = 0V. Data pins can tolerate up to 5.5V The PAUSB42 is compatible with 1.8 and 1.4V Systems.
