USB 1.1/2.0 full speed USB PHY

 CT25201 is a complete, full featured and scalable USB1.1 and 2.0 full speed controller. It features the CT25201_PHY IP, implementing the analog front-end PHY interface and CT20101, the auto calibrating RC Oscillator designed for USB application to generate 48MHz without any external quartz that have been integrated with the digital controller.

The IP has been designed in order to allow professional and fast-track synthesis/ back-end on standard CMOS libraries.
Specific logic has been added to enable integration with the CT20602 family of IPs enabling the development of Type-C Port Controllers (TCPC), USB-PD Complete Controllers or custom controllers for Active Cables or USB-C embedded functions.
