Revision History
Overview
The Tsi721 Datasheet provides signal, electrical, and packaging information about the Tsi721. It is intended for hardware
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 “n”. 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.
Differential Signal Notation
Differential signals consist of pairs of complement positive and negative signals that are measured at the same time to
determine a signal’s active or inactive state (they are denoted by “_p” and “_n”, respectively). The following table illustrates the
differential signal naming convention.
State Single-line signal Multi-line signal
Active low NAMEn NAMEn[3]
Active high NAME NAME[3]
State Single-line signal Multi-line signal
Inactive NAME_p = 0
NAME_n = 1
NAME_p[3] = 0
NAME_n[3] = 1
Active NAME_p = 1
NAME_n = 0
NAME_p[3] is 1
NAME_n[3] is 0
