TS3USB30E

具有单独使能和 ESD 保护的高速 USB 2.0 1:2 多路复用/多路解复用开关

The is a high-bandwidth 1:2 switch specially designed for the switching of high-speed USB 2.0 signals in handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os. The wide bandwidth 900 MHz of this switch allows signals to pass with minimum edge and phase distortion. The device multiplexes differential outputs from a USB host device to one of two corresponding outputs, or from two different hosts to one corresponding output. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. It is designed for low bit-to-bit skew and high channel-to-channel noise isolation, and is compatible with various standards, such as high-speed USB 2.0 480 Mbps.

The TS3USB30E integrates ESD protection cells on all pins, is available in a tiny UQFN package 1.8 mm × 1.4 mm or a VSSOP package, and is characterized over the free-air temperature range of –40°C to 85°C.
