4-Channel High-Performance Differential Switch

4-Channel High-Performance Differential Switch - HD3SS3412A
 

Description

The HD3SS3412A 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 or server application. With its bidirectional capability, the HD3SS3412A also supports applications that allow connections between one target and two source devices, such as a shared peripheral between two platforms. The HD3SS3412A 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 HD3SS3412A 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.

The HD3SS3412A is a generic 4-CH high-speed MUX/de-MUX 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 HD3SS3412A will also support several other high-speed data protocols with a differential amplitude of <1800 mVpp and a common-mode voltage of < 2.0 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 a microcontroller.
