UM7222MA/7222/7222A High-Speed USB2.0 (480 Mbps) DPDT Switch UM7222MA MSOP10 UM7222 QFN10 1.8×1.4 UM7222A QFN10 2.1×1.6 General Description The UM7222MA/UM7222/UM7222A is a dual port high-speed, low-power data switch optimized for USB 2.0 signal switching. The UM7222MA/UM7222/UM7222A switch is configured in double-pole/ double-throw DPDT. It handles bidirectional signal flow, achieving a 550 MHz -3dB bandwidth, and a port to port crosstalk and isolation at -50dB at 250MHz. The UM7222MA/UM7222/UM7222A operates from a single +2.7V to +5.5V supply, with current consumption less than 1 microampere. The UM7222MA/UM7222/UM7222A features wide bandwidth and low bit-to-bit skew allow it to pass high-speed differential signal with good signal integrity, offers little or no attenuation of the high-speed signals at the outputs. Its high channel-to-channel crosstalk rejection results in minimal noise interface. Its bandwidth is wide enough to pass high-speed USB 2.0 differential signals (480Mbps). The control logic threshold is guaranteed to be compatible with 1.8V logic. The UM7222MA is available in Pb-free MSOP10 package, the UM7222 is available in Pb-free QFN10 package (1.4mm×1.8mm×0.55mm), while the UM7222A is available in Pb-free QFN10 package (2.1mm×1.6mm×0.55mm), they are ideal for portable high speed mix signal switching application.

The UM7222 has specially designed circuitry which prevents unintended signal bleed through as well as guaranteed system reliability during a power-down, over-voltage condition. The protection has been added to the common pins (D+, D-). Power-On Protection The USB 2.0 specification also notes that the USB device should be capable of withstanding a VBUS short during transmission of data. This modification works by limiting current flow back into the V+ rail during the over-voltage event so current remains within the safe operating range. In this application, the switch passes the full 5.25V input signal through to the selected output while maintaining specified off isolation on the un-selected pins. ________________________________________________________________________ http://www.union-ic.com Rev.08 Jan.2015 8/12 UM7222MA/7222/7222A Package Information UM7222MA MSOP10 Outline Drawing D DIMENSIONS E E1 L θ Symbol MILLIMETERS INCHES Min Typ Max Min Typ Max A - - 1.10 - - 0.043 A1 0.00 - 0.15 0.000 - 0.006 A2 0.75 0.85 0.95 0.030 0.033 0.037 A3 0.25 0.35 0.39 0.010 0.014 0.015 b 0.18 - 0.27 0.007 - 0.011 INDEX 2 1 e b c 0.15 - 0.20 0.006 - 0.008 2.90 3.00 3.10 0.114 0.118 0.122 E 2.90 3.00 3.10 0.114 0.118 0.122 E1 4.70 4.90 5.10 0.185 0.193 0.201 e 0.40 0.50 0.60 0.016 0.020 0.024 L 0.40 0.60 0.80 0.016 0.024 0.031 θ 0º - 8º 0º - 8º End View A3 A1 A A2 Top View c D Side View Land Pattern 0.5 5.7 2.5 1.6 4.1 0.3 NOTES: 1.
