The TS3USB31 is a high-bandwidth 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 (750 MHz) of this switch allows signals to pass with minimum edge and phase distortion. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. It 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 TS3USB31 is a high‑bandwidth, bidirectional switch designed for routing high‑speed USB 2.0 (480 Mbps) signals in handheld and consumer devices such as cell phones, digital cameras, and notebooks. It supports operation at 3 V to 4.3 V, offers low power consumption (1 µA max), and includes ESD protection per JESD‑22 standards.
Key features include a typical on‑state resistance of 10 Ω, a 3‑dB bandwidth of 1220 MHz, propagation delay of 0.25 ns, and low crosstalk (53 dB) and isolation (30 dB) performance. The device is supplied in an 8‑pin TQFN package and is compatible with USB 1.0, 1.1, and 2.0 signaling.
