Description

The HD3SS2521 is an integrated DockPort switch solution. It provides independent 2:1 passive switching for the SuperSpeed USB and Display Port signals as well as for the USB 2.0 (HS/FS/LS) and I2C necessary to support DockPort applications. In addition, a firmware upgradable integrated DockPort controller is provided to manage host and dock side DockPort detection, signal switch and power configuration.

The HD3SS2521 is offered in 56-pin WQFN package and is specified to operate from a single supply voltage of 3.3V over the temperature range of 0°C to 70°C .
