Texas Instruments HD3SS3412RUAR
The HD3SS3412 device is a high-speed passive switch capable of switching fourdifferential channels, including applications such as two full PCI Express x1 lanes from one sourceto one of two target locations in a PC/server application. With its bidirectional capability theHD3SS3412 also supports applications that allow connections between one target and two sourcedevices, 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 PortC.
The HD3SS3412 is offered in an industry standard 42-pin WQFN package available in acommon footprint shared by several other vendors. The device is specified to operate from a singlesupply voltage of 3.3 V over the full temperature range of -40°C to 85ºC.
The HD3SS3412 is a generic 4-CH high-speed MUX/de-MUX type of switch that can be used forrouting high-speed signals between two different locations on a circuit board. Although it wasdesigned specifically to address PCI Express Gen III applications, the HD3SS3412 will also supportseveral other high-speed data protocols with a differential amplitude of <1800 mVpp and acommon-mode voltage of < 2 V, 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 amicrocontroller.
