PAUSB42
LoPro^™ DPDT USB2.0 (480Mbps) Switch
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 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.
