HD3SS3415RUAR

The HD3SS3415RUAR from Texas Instruments is a high-performance 4-channel analog differential switch designed for high-speed signal routing. It operates with a supply voltage of 3.3V ±10% and supports multiple interface standards, including PCI Express Gen III and USB 3.1, with a wide -3dB differential bandwidth exceeding 8 GHz.

This switch features excellent dynamic characteristics, including low insertion loss of -1.5 dB, high off-isolation of -19 dB, and low return loss of -11 dB at 4 GHz. The typical on-resistance is 5000 mΩ, with a maximum of 8000 mΩ. It is capable of switching four differential channels and is bidirectional, making it suitable for applications requiring routing between different locations on a circuit board or shared peripherals between platforms.

The HD3SS3415RUAR is housed in a compact 42-pin WQFN package measuring 3.5 mm x 9 mm, featuring an exposed pad for improved thermal performance. It is specified for an operating temperature range of 0°C to 70°C (TA). The device utilizes a single control line (SEL Pin) to manage signal paths between ports, offering a 2:1 configuration for its four channels.

Applications include PC/server systems needing to switch two full PCI Express x1 lanes from one source to one of two target locations. Its generic mux/demux functionality also makes it versatile for various high-speed signal routing needs.
