LoPro^™ DPDT USB2.0 Switch
Description
ProTek Analog’s PA2983, PA2983L 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 1GHz allows passing of the 3^rd Harmonic,
resulting in minimal edge and phase distortion.
Superior channel to channel crosstalk minimizes interference.
