About the USB2 Options
USB 2.0 is a version of the Universal Serial Bus specification, which is used to connect a host controller
(typically a PC) to various devices. The 2.0 version brought a higher maximum bandwidth (480 Mb/s) and
features such as the Mini-B Connector, Battery Charging, and Micro-USB Cables and Connectors
specifications, to name a few.
High-Speed Inter-Chip (HSIC) technology communicates between microchips in an embedded sub-system
and leverages the traditional host-device topology of USB, utilizing a large amount of existing USB code. This
makes HSIC extremely lucrative in areas demanding fast time-to-market solutions, such as the mobile
industry including both smart phones and tablets.
USB standards are maintained by the non-profit USB Implementers Forum, Inc. (USB-IF). Additional
information, including specifications for specific versions, can be found on their website at www.usb.org/.
Decode
The USB2bus and USB2-HSIC decoder options apply software algorithms to extract packet-level data
consistent with the HSIC, USB 2.0, USB 1.1, and USB 1.0 standards from physical layer waveforms measured
on your oscilloscope. Token, Data, and Status information is displayed over the actual physical layer
waveforms, color-coded to provide fast, intuitive understanding of the relationship between USB packets and
other, time synchronous events.
Trigger
The USB2 TD (trigger and decode) option additionally allows triggering on predefined and user-defined
patterns in USB packets, errors, transactions, or bus events.
