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
