Product details

1 GHz bandwidth and USB 2.0 signal switching

The MAX4989ETD+T is a 2:4 crosspoint switch from Analog Devices, designed to route high-speed differential signals with a -3 dB bandwidth of 1 GHz. This bandwidth comfortably covers USB 2.0 (480 Mbps) and similar LVDS or video signals, preserving edge rates and eye openings through the switch matrix. With a maximum on-state resistance of 9 Ohm, the switch introduces minimal attenuation and maintains signal integrity across the 2:4 multiplexer/demultiplexer topology. The single-channel configuration routes one differential pair to one of four outputs, or vice versa, making it suitable for USB port sharing or signal routing in test equipment.

Lifecycle and compliance status

It is fully RoHS3 compliant, meeting the latest EU directive requirements for lead-free soldering processes. Packaging options include Tape & Reel (TR) and Cut Tape (CT), both suitable for automated pick-and-place assembly.
