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.
