IP2 USB 2.0

This course covers USB2.0


Objectives
	The course details the hardware implementation and describes the tests required to check the compliance of an equipment.
	All interconnect standards between Link and PHY are explained: UTMI, UTMI+, ULPI as well Inter-Chip USB.
	An architectural view of an USB system implementing low speed, full speed and high speed devices is described.
	The course details the various steps of the bus enumeration sequence.
	Packet format and USB transactions are taught with the assistance of the Lecroy USB analyser.
	The course details the requirements of the EHCI specification.
	HID class device specification and mass-storage classes are covered on request.
A Lecroy USB analyser is used to capture and display USB traffic. •A lot of traces are included in the material.
A more detailed course description is available on request at info@ac6-training.com


Prerequisites
	Experience of a digital bus is mandatory.
