describe
Ts3usb221a device is a high bandwidth switch specially designed to switch high-speed USB 2.0 signals in handheld devices and consumer applications (such as mobile phones, digital cameras and laptops with hubs or controllers), with limited USB I / O. The wideband (900 MHz) of the switch allows the signal to pass with less edge and phase distortion.
The device multiplexes the differential output of the USB host device to one of the two corresponding outputs. The switch is bidirectional, and the high-speed signal at the output has little attenuation. The device also has a low power consumption mode, which can reduce the power consumption of battery or portable applications with limited power budget to 1 μ a。 The device is designed for low in place tilt and high channel to channel noise isolation and is compatible with various standards, such as high-speed USB 2.0 (480 Mbps).
The ts3usb221a device integrates ESD protection unit on all pins and adopts micro μ QFN package (2 mm) × 1.5 mm), which is characterized by a free air temperature range of - 40 ° C to 85 ° C.
