Texas Instruments HD3SS3412A 4-Ch Differential Switches
Texas Instruments HD3SS3412A 4-Channel High-Performance Differential Switches are high-speed and capable of switching between four differential channels. The HD3SS3412A is designed for switching applications such as two full PCI Express x1 lanes from one source to one of two target locations in a PC or server application. The HD3SS3412A has bi-directional capabilities and supports applications that allow connections between one target and two source devices. The switches have 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 MUX/de-MUX type of switch can be used for routing high-speed signals between two different locations on a circuit board. The device is specified to operate from a single supply voltage of 3.3V over the full temperature range of 0°C to 70°C.
