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 QFN package available in a common footprint shared by several other vendors. The device is specified to operate from a single supply voltage of 3.3V over the full industrial temperature range of –40°C to 85ºC
The HD3SS3415 is a generic 4-CH high speed mux/demux type of switch that can be used for routing high-speed signals between two different locations on a circuit board. Although it was designed specifically to address PCI Express Gen III applications, the HD3SS3415 will also support several other high-speed data protocols with a differential amplitude of <1800mVpp and a common mode voltage of<2.0V, as with USB 3.0 and DisplayPort 1.2. The device’s one select input (SEL) pin can easily be controlled by an available GPIO pin within a system or from a micro-controller.
Compatible with Multiple Interface Standards Operating up to 12Gbps Including PCI Express Gen III and USB 3.0
