3 Description
The HD3SS3412 device 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 HD3SS3412 also supports applications
that allow connections between one target and two
source devices, such as a shared peripheral between
two platforms. The HD3SS3412 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 HD3SS3412 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 70ºC.
