Description
Pericom Semiconductor’s PI3USB series of logic circuits are produced using the Company’s advanced sub-micron CMOS technology, achieving industry leading performance. The PI3USB10 is a 4- to 2-Channel multiplexer/demultiplexer USB 2.0 Switch with Hi-Z outputs. Industry leading advantages include a propagation delay of less than 250ps, resulting from its low channel resistance and I/O capacitance. 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, high channel-to-channel noise isolation and is compatible with various standards, such as High Speed USB 2.0 (480 Mb/s).
Application
• Routes signals for USB 2.0
