♦General Description
ASM1542 is a 2 differential pairs, 2:1 mux or 1:2 demux passive switch, using for high speed signal switch
application, supporting up to 10Gbps data rate with AC coupled signals, offering low attenuation signal quality, low
bit-tbit skew and high channel to channel noise isolation. ASM1542 can be used for not only PCIe and SATA but also SuperSpeedPlus USB and Thunderbolt2 interface. For example, ASM1542 can be used on USB3.1 Type-C connector to support the advance function of flip-able.
