USB peripheral controller supports data rates up to 20 Gbits/s

October 2, 2025

Issue 7 2025

The EZ-USB™ FX20 from Infineon is a fully integrated USB peripheral controller which provides a complete solution for USB connectivity in embedded devices. It is backed by a full-featured development kit with software support.

The EZ-USB FX20 USB peripheral controller from Infineon extends the capabilities of the EZ-USB family to add support for the latest ultra-fast 20 Gbits/s USB and LVDS interfaces.  

 

The Infineon family of USB peripheral controllers also includes the EZ-USB FX10, which uses one lane of USB 3.2 Gen2 PHY to transfer data at a rate of up to 10 Gbits/s. The Infineon USB 3.2 PHY circuitry provides dynamic programmability: this allows the designer to implement the optimal connection to transfer signals over a passive USB cable up to 5 m long, at a data transfer rate of up to 8.8 Gbits/s.
