Product Description

The UM7227QA/UM7227MA is a dual port high-speed, low-power data switch optimized for USB 2.0 signal switching. The UM7227QA/UM7227MA switch is configured in double-pole/double-throw DPDT. It handles bidirectional signal flow, achieving a 750 MHz -3dB bandwidth, and a port to port crosstalk and isolation at -42dB at 250MHz.

The UM7227QA/UM7227MA operates from a single +2.7V to +5.5V supply, with current consumption less than 1 uA.

The UM7227QA/UM7227MA 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 UM7227QA is available in Pb-free QFN10 package (1.4mm×1.8mm×0.55mm), the UM7222MA is available in Pb-free MSOP10 package . They are ideal for portable high speed mix signal switching application.
