FSUSB20 is a low-power high-bandwidth switch specially designed for switching 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 (>720MHz) of this switch allows signals to pass with minimum edge and phase distortion. Superior channel-to-channel crosstalk results in minimal interference. It is compatible with the high-speed USB 2.0 standard.
The FSUSB20 is a low‑power, high‑bandwidth switch designed for high‑speed USB 2.0 signals in handheld and consumer devices such as cell phones, PDAs, digital cameras, and notebooks. It offers -30 dB off isolation at 250 MHz and -30 dB non‑adjacent channel crosstalk at the same frequency, ensuring minimal interference.
Key electrical specifications include a typical on‑resistance of 4.5 Ω, a supply voltage range of -0.5 V to +4.6 V, and a 3 dB bandwidth of approximately 720 MHz. The device is available in several Pb‑free packages (MicroPak™, DQFN, MSOP) and meets JEDEC standards for reliability.
