NCN1188
3:1 High Speed USB Switch with Audio and MHL Capability
The NCN1188 allows portable systems to share a single USB 2.0 or 3.0 receptacle to transmit and receive paired signals from three separate locations. All of the three differential channels are compliant to High Speed USB 2.0, Full Speed USB 1.1, Low Speed USB 1.0 and any generic UART protocol. The two dedicated high speed data paths also support Mobile High Definition Link (MHL) video up to resolutions of 1080i (2.25 Gbps) and 1080p (3 Gbps in Packed Pixel mode). The multi−purpose audio path is capable of passing signals with negative voltages as low as 2 V below ground and features shunt resistors to reduce Pop and Click noise in the audio system. The NCN1188 is housed in a space saving, ultra low profile 2.0 x 1.7 x 0.
