3 Description
The HD3SS3415 is a high-speed passive switch
capable of switching four differential channels,
including applications such as two full PCI Express x1 lanes from one source to one of two target locations
in a PC/server application. With its bidirectional
capability the HD3SS3415 will also support
applications that allow connections between one
target and two source devices, such as a shared
peripheral between two platforms. The HD3SS3415
has a single control line (SEL Pin) which can be used
to control the signal path between Port A and either
Port B or Port C.
The HD3SS3415 is offered in an industry standard
42-pin WQFN package available in a common
footprint shared by several other vendors. The device
is specified to operate from a single supply voltage of
3.3 V over the full temperature range of 0°C to 70°C
