PI3USB221 High-Speed USB2.0 1:2 Multiplexer/ DeMultiplexer Switch with Signal Enable Description Features The PI3USB221 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 (1.1 GHz) of this switch allows signals to pass with minimum edge and phase distortion. The device multiplexes differential outputs from a USB host device to one of two corresponding outputs. 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). • VDD Operation at 2.5 V and 3.3 V • VI/O Accepts Signals up to 5.5 V • 1.8-V Compatible Control-Pin Inputs • Low-Power Mode When OE Is Disabled (2 µA) • rON = 6Ω Maximum • ΔrON = 0.2Ω Typical • Cio(on) = 6 pF Maximum • Low Power Consumption (50 µA Maximum) • ESD > 8kV contact on USB signal path per IEC61000-4-2) • High Bandwidth (1.1 GHz Typical) • Packaging (Pb-free & Green): - 10-contact, TDFN (ZE10) - 10-contact, TLLGA (XA10) Applications • Routes Signals for USB 1.0, 1.1, and 2.0 • Mobile Industry Processor Interface (MIPI) Signal Routing Pin Configuration TLLGA Package (Top View) TLLGA Package (Bottom View) 1 10 1D- 2 9 S 2D+ 3 8 D+ 2D- 4 7 D- 5 6 OE 1 9 09-0004 S 10 1D- 2 8 D+ 2D+ 3 7 D- 2D- 4 6 OE 5 GND GND 1D+ 1 S 9 10 1 1D+ D+ 8 2 1D- D- 7 3 2D+ OE 6 4 2D- 5 GND VDD 1D+ VDD VDD TDFN Package (Top View) PS9053 10/28/09 PI3USB221 High-Speed USB2.0 1:2 Multiplexer/ DeMultiplexer Switch with Signal Enable Block Diagram D+ 1D+ D- 1D- 2D+ 2D- CONTROL LOGIC Pin Description NAME OE S D nD Truth Table S X L H 09-0004 S OE DESCRIPTION Active LOW, Output enable Select input COM port I/O for USB data path (port 1 and port 2) OE H L L FUNCTION Disconnect D = 1D D = 2D 2 PS9053 10/28/09 PI3USB221 High-Speed USB2.0 1:2 Multiplexer/ DeMultiplexer Switch with Signal Enable ABSOLUTE MAXIMUM RATINGS1 Over operating free-air temperature range (unless otherwise noted) VDD Supply Voltage Range.................................................. –0.5V to 4.6V VIN Control Input Voltage Range2, 3....................................... –0.5V to 7V VI/O Switch I/O Voltage Range2, 3, 4....................................... –0.5V to 7V IIK Control Input Clamp Current (VIN < 0)..................................... –50mA II/OK I/O Port Clamp Current (VI/O < 0).......................................... –50mA II/O ON-state Switch Current5....................................................... ±120mA Continuous current through VDD or GND..................................... ±100mA θJA Package Thermal Impedance TLLGA Package ............................................................... 48.7°C/W TDFN Package . ................................................................ 243°C/W Tstg Storage temperature range...............................................–65 to 150°C Notes: 1. Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. All voltages are with respect to ground, unless otherwise specified. 3. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 4. VI and VO are used to denote specific conditions for VI/O. 5.

VIN and IIN refer to control inputs. 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 input and output terminals at the indicated current through the switch. ON-state resistance is determined by the lower of the voltages of the two terminals.

For Max or Min conditions, use the appropriate value specified under Electrical Characteristics for the applicable device type. 2. Specified by design 3. The 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. 09-0004 5 PS9053 10/28/09 PI3USB221 High-Speed USB2.0 1:2 Multiplexer/ DeMultiplexer Switch with Signal Enable Application Information Figure 5: HS Eye Test Setup Test Result Test Result 1: High-speed, Up-stream, Near-end Eye of PI3USB221 09-0004 6 PS9053 10/28/09 PI3USB221 High-Speed USB2.0 1:2 Multiplexer/ DeMultiplexer Switch with Signal Enable PARAMETER MEASUREMENT INFORMATION VDD 1D or 2D VOUT1 or VOUT2 VIN VCTRL D CL(2) 1D or 2D RL S CL(2) Logic Input(1) RL GND TEST RL CL VCOM tON 500-Ohm 50 pF V+ tOFF 500-Ohm 50 pF V+ Logic Input (VI) 50% (2) 0 tON Switch Output (VOUT1 or VOUT2) (1) 1.8 V 50% tOFF 90% 90% VOH VOL All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, ZO = 50-Ohm , tr < 5 ns, tf < 5 ns.
