HIGH-SPEED(480Mbps) USB2.0 DPDT SWITCH

DESCRIPTION

The KUSB50QN is a High-Speed(480Mbps) USB2.0 signal switch.

Configured as a double-pole double-throw (DPDT) switch, it is optimized

for switching between 2 Hi-Speed sources or a Hi-Speed(480Mbps) and

Full-Speed(12Mbps) source. Its wide Bandwidth (720MHz) is wide enough

to pass High-Speed USB2.0 differential signals. Industry-leading advantages

include a propagation delay of less than 250ps, resulting from its low channel

resistance and low on capacitance. It is bidirectional and offers little or no

attenuation of the High-Speed signal at the outputs.

Its high channel-to-channel crosstalk rejection results in minimal noise

interference. The switch is designed to minimize current consumption even

KUSB50QN also offers over-voltage protection per the USB2.0 Specification.

With the chip powered ON or OFF, all data I/O pins can withstand a short to

Vbus(5.25V).

FEATURES
