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 .
