Agenda

• What is different about USB 2.0
• Technical Challenges
• Product Family Overview
• Competitive Issues
• Resources Available To You
• Question Time

3
What is USB 2.0?

• Peripheral interconnect bus
• Serial bus with data transfer of 420Mb/s
• Continuation of the USB 1.1 specification
• Hot plug-and-play standard

USB 1.1 2.0 Similarities

• Connectors and cables are the same
• 2.0 is backwards compatible with 1.1
• No difference in use model to end user
• Market is currently PC centric

5
USB 2.0 Changes

• Max data rate is 480 Mb/s (40X increase)
• Windows 2000 or XP only
• Stringent current tests
• Critical signal integrity measurements
• Auto speed sensing 1.5/12/480 Mb/s

6
What Are The Challenges?

• 480 Mb/s is a 40X increase
• USB 2.0 devices must be compatible with USB 1.1
• A hub must communicate with up to 7 peripheral
  devices and 5 hubs.
• Data transfer rates of 1.5Mb/s, 12Mb/s, 420Mb/s,
  isochronous, and bulk
• Current and signal integrity requirements are
  stringent

7
Typical Problems

• Enumeration Failure
• Bad End of Packet
• Inrush current exceeds specification
• Data valid window on D and D- outside of limits
• Device fails to go into suspend mode

Agilent Provides Complete Integration of Analog
Digital Debug

• Compliance testing with USB scripts and MatLab in
  Infiniium
• Debug with FuturePlus USB 2.0 analysis probe and
  logic analyzer
• Combining Oscilloscope and Logic Analysis
  Measurements (E5850A)
