描述 Description

The HD3SS0001 is a high-speed passive-switch device with integrated buffers and resistors, designed to support Thunderbolt? technology, DisplayPort, and Dual Mode DisplayPort. The 10G path supports a high 10GHz bandwidth and excellent loss characteristics, while the DisplayPort path supports 5.4Gbps.The integrated 3-pairs to 1-pair multiplexer (3:1 MUX) switches between DDC, AUX, and 10.3Gbps signals. The integrated 2-pairs to 1-pair multiplexer (2:1 MUX) switches between the Thunderbolt? technology Low Speed UART transmit/receive pair and DisplayPort Main Link 1.The MUXs are controlled by 4 input pins: TRI#, DP_EN#, 10G_EN, and CAD_IN (cable detect from the connector). The HD3SS0001 is packaged in a small 3x3mm 24-pin QFN, operates from a single 3.3V supply, and supports an ambient temperature range of –40°C to 85°C.
