AN5038 is intended to expedite the developer's learning curve regarding the migration of a CY7C65640A (EZ-USB® HX2™) design to use the CY7C65630 (HX2LP™) hub.

Introduction

The HX2LP family is next-generation USB high-speed hubs. This family of hubs includes a two-port hub (CY7C65620) with a single transaction translator (TT), and a 4-port hub with a single TT (CY7C65630). The HX2LP family reduces the power consumption of the HX2 while minimizing the effects on existing designs. This Application Note highlights the difference between the products, and aids the designer in migrating existing designs to the HX2LP family.
