Description

The PI3USB32 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 bidirec- tional 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 vari- ous standards, such as high-speed USB 2.0 (480 Mbps).

VIN and IIN refer to control input (OE). VI, VO, II, and IO refer to data pins. 2. All typical values are at VDD = 3.3 V (unless otherwise noted), TA = 25°C. 3. For I/O ports, the parameter IOZ includes the input leakage current. 4. This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VDD or GND. 5. Measured by the voltage drop between the D and HSD terminals at the indicated current through the switch. ON-state resistance is determined by the lower of the voltages of the two terminals. 10-0146

Guaranteed by design. 3. The bus switch contributes no propagational delay other than the RC delay of the on resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25 ns for 10-pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side. 10-0146
