FSUSB42MUX Description
A bi-directional, low-power, two-port, high-speed USB 2.0 switch is the FSUSB42MUX. It is designed to switch between two Hi-Speed (480 Mbps) sources or a Hi-Speed and Full-Speed (12 Mbps) source. It is configured as a double-pole, double-throw (DPDT) switch. The FSUSB42 has an incredibly low on capacitance (CON) of 5.5 pF and complies with USB 2.0 specifications.
This device's broad bandwidth (720 MHz) surpasses the bandwidth required to pass the third harmonic, producing signals with minimal phase distortion and edge. Improved crosstalk between channels reduces interference as well. For applications when the VCC supply is shut off (VCC=0), the FSUSB42 has additional circuitry on the switch I/O pins that enables the device to tolerate an over-voltage state. Even in situations where the control voltage provided to the SEL pin is less than the supply voltage (VCC), this device is made to reduce current usage. This particular feature, which enables direct communication with the generalpurpose I/Os of the baseband processor, is particularly useful for ultra-portable applications like cell phones. Additional uses for switching and connection sharing can be found in PDAs, digital cameras, printers, notebook computers, and portable cell phones.
