PI3USB32 High-Speed USB 2.0 (480 Mbps) 1-Port Switch with Full Power Down Feature Features Description · VDD Operation at 3 V and 4.3 V 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 bidirectional 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 various standards, such as high-speed USB 2.0 (480 Mbps). · 1.8-V Compatible Control-Pin Inputs · IOFF Supports Full Power-Down Mode Operation · ron = 6-Ohm Typical · Dron <0.35-Ohm Typical · Cio(ON) = 5 pF Typical · Low Power Consumption · ESD Performance – 7kV Human-Body Model, per JESD22 spec (A114-B, Class II) – 1000-V Charged-Device Model (C101) – ±4kV contact, per IEC61000-4-2 · Wide –3-dB Bandwidth = 2110 MHz Typical · Packaged in 8-Pin TQFN (1.5 mm ´ 1.5 mm) Application • Routes Signals for USB 1.0, 1.1, and 2.0 1 OE D+ 6 5 4 8 VDD HSD1+ D- 7 2 HSD+ Block Diagram GND 3 D+ NC (Top View) HSD- Pin Configuiration D+ Control 1 2 3 7 6 5 D- NC = No Internal Connection 10-0146 1 4 8 VDD HSD- OE HSD+ D- NC HSD1- OE (Bottom View) GND PS9010B 03/25/10 PI3USB32 High-Speed USB 2.0 (480 Mbps) 1-port Switch with Full Power Down Feature Pin Description Name Description OE Bus-switch enable D+, D-, HSD+, HSD- Data ports NC No connect OE Description H Disconnect L D+, D- = HSD+, HSD- Truth Table Absolute Maximum Ratings(1) (Over operating free-air temperature range unless otherwise noted.)

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 3 PS9010B 03/25/10 PI3USB32 High-Speed USB 2.0 (480 Mbps) 1-port Switch with Full Power Down Feature Dynamic Electrical Characteristics (over operating range, TA = –40°C to 85°C, VDD = 3.3 V ± 10%, GND = 0 V) Parameter Test Conditions(1) Description OIRR OFF isolation RL = 50-Ohms, f = 240 MHz BW Bandwidth (-3 dB) RL = 50-Ohms Typ.(1) Units -30 dB 2110 MHz Xtalk Crosstalk RL =50-Ohms, f = 240 MHz -55 dB Notes: 1.

For Max or Min conditions, use the appropriate value specified under Electrical Characteristics for the applicable device type. 2. 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 4 PS9010B 03/25/10 PI3USB32 High-Speed USB 2.0 (480 Mbps) 1-port Switch with Full Power Down Feature Application Information VDD PI3USB32 D+ Base Band Prrocessor or FS USB Controller USB Connector D- OE HS USB Controller Application Diagram 10-0146 5 PS9010B 03/25/10 PI3USB32 High-Speed USB 2.0 (480 Mbps) 1-port Switch with Full Power Down Feature VDD HSD+ VD+ VHSD+ D+ (B) CL OE RL TEST RL t ON 50 Ω VDD t OFF 50 Ω VDD Logic Input (V OE) GND CL 50% Switch Output (HSD+) 1.8 V 50% t ON VOE(A) VIN 0 t OFF 90% 90% VOH VOL Turn-On (tON) and Turn-Off Time (tOFF) VDD Network Analyzer VOUT 50 Source Signal HSD+ D+ 50 50 VIN Channel OFF: HSD to D+ VOE = VDD Network Analyzer Setup VOE + Source Power = 0 dBm (632-mV P-P at 50- load) DC Bias = 350 mV OE GND Figure 8.
