About this Document
This section discusses the following topics:
•“Scope” on page 3
•“Document Conventions” on page 3
•“Revision History” on page 4
Scope
The Tsi350A PCI-to-PCI Bridge User Manual discusses the features, capabilities, and configuration
requirements for the Tsi350A. It is intended for hardware and software engineers who are designing
system interconnect applications with the device.
Document Conventions
This document uses the following conventions.
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.
Object Size Notation
•Abyte is an 8-bit object.
•Aword is a 16-bit object.
•Adoubleword (Dword) is a 32-bit object.
Numeric Notation
• Hexadecimal numbers are denoted by the prefix 0x (for example, 0x04).
State Single-line signal Multi-line signal
Active low NAME_b NAMEn[3]
Active high NAME NAME[3]

• Binary numbers are denoted by the prefix 0b (for example, 0b010).
• Registers that have multiple iterations are denoted by {x..y} in their names; where xis first register
and address, and yis the last register and address. For example, REG{0..1} indicates there are two
versions of the register at different addresses: REG0 and REG1.

Revision History
80D5000_MA001_08, Formal, September 2009
This document was rebranded as IDT. It does not include any technical changes.
80D5000_MA001_07, Formal, April 2008
This document supports the production version of the Tsi350A. The asynchronous mode functionality
was removed from this document. Information has been removed from “Secondary Clock Outputs” on
page 84 and pin 52 in “208-pin PQFP Pin List” on page 104 was changed from ASYNC_MODE to
VSS.
80D5000_MA001_06, Formal, January 2008
This document supported the production version of the Tsi350A. The Tsi350A is a performance
enhancement of the Tsi350 and there are no functional changes between the devices. All technical
information in this document applies to both the Tsi350 and the Tsi350A.
Tip
This symbol indicates a basic design concept or information considered helpful.
This symbol indicates important configuration information or suggestions.
This symbol indicates procedures or operating levels that may result in misuse or damage to
the device.
