Description

The PI3USB221A 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).

The USB221A offer over voltage protection for the D+/D- pins as per the USB2.0 specification. With the chip power on or off if D+/D- pins are shorted to Vbus(5V+/-5%), a less than 3.8V(typ) signal will transmit through 1D+/1D- and 2D+/2D1 output.

Feature(s)

  • 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)
  • Over Voltage Protection
  • Packaging (Pb-free & Green): UQFN-10 and UDFN-10

Application(s)

  • Routes signals for USB 2.0
  • PC, Notebooks and Hand-held devices
