General Description
The ET7222 is a 2CH single-pole/double-throw (SPDT) switches. Their wide bandwidth and low bit-to-bit skew allow them to pass high-speed differential signals with good signal integrity.
Each switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. Industry-leading advantages include a propagation delay of less than 250 ps, resulting from its low channel resistance and low I/O capacitance. Their high channel-to-channel crosstalk rejection results in minimal noise interference. Their bandwidth is wide enough to pass High-Speed USB 2.0 differential signals (480 Mb/s).
ET7222 is offered in a QFN10L and MSOP10 package.
