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.
