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 switching between two 480Mbps sources

or a Hi-speed and Full-speed 12Mbps source.

The bandwidth of 895MHz allows passing of the 3rd Harmonic,

resulting in minimal edge and phase distortion.

Superior channel to channel crosstalk minimizes interference.

The PAUSB42 contains circuitry for Power-Off protection when VCC

= 0V. Data pins can tolerate up to 5.5V

The PAUSB42 is compatible with 1.8 and 1.4V Systems.
