ASM1543
Type C Mux
ASM1543 is a one Four to two differential channels mux switch with integrated Type-C Configuration Channel Logic Circuitry, using for USB3.1 type-C mux and CC detection application. The signal performance of mux switch is up to 10Gbps SuperSpeedPlus USB bus with low insertion loss and return loss, and it also supports USB plug orientation, configurable as DFP role or UFP role through the setting of strapping pins, and implementing the strapping for the setting/detection of Type-C current mode, following USB3.1 Revision 1.0 and USB Type-C Connector and Cable Revision 1.3 standard specification. ASM1543 also integrates CC bus voltage detector, and internal Ip current/Rd resistors and internal power switch with overcurrent protection to support VCONN 5V supply, using an industry standard 32 pins QFN Green package, compliant with RoHS, operating at 3.3V supply voltage for chip and 5V voltage for VCONN supply on e-mark cable.
