Scope
The
Tsi572 Hardware Manual
discusses electrical, physical, and board layout information for
the Tsi572. It is intended for hardware engineers who are designing system interconnect
applications with these devices.
Document Conventions
This document uses a variety of conventions to establish consistency and to help you quickly
locate information of interest. These conventions are briefly discussed in the following sections.
Non-differential Signal Notation
Non-differential signals are either active-low or active-high. An active-low signal has an active
state of logic 0 (or the lower voltage level), and is denoted by a lowercase “b”. An active-high
signal has an active state of logic 1 (or the higher voltage level), and is not denoted by a special
character. The following table illustrates the non-differential signal naming convention.
