Evaluation Module Overview
1 Evaluation Module Overview
1.1 Introduction
The TXV-EVM evaluates the operation of the low skew
The EVM also evaluates devices with similar foot prints such as SN74AVC8T245RHL, SN74AXC8T245RHL,
SN74LVC8T245RHL and SN74LXC8T245RHL.
This user's guide describes the characteristics, operation, and use of the TXV-EVM evaluation module built
for TXV low skew voltage translators. A complete printed-circuit board layout, schematic diagram, and bill of
materials are included in this document.
1.2 Kit Contents
Table 3-2
lists the EVM bill of materials for both the TXV0106-EVM and TXV0108-EVM.
The TXV0106-EVM and TXV0108-EVM contains the populated components as shown in
disclaimer.
1.3 Specification
Refer to the TXV or the Pin-to-Pin (P2P) data sheets for the device recommended conditions and specifications.
See
Table 2-3
for the corresponding data sheets.
1.4 Device Information
The TXV010x devices are 6-bit and 8-bit, dual-supply fixed and direction controlled low-skew voltage translation
devices. The devices can be used for buffering, redriving, voltage translation, and power up isolation on timing-
margin sensitive interfaces, such as Reduced Gigabit Media Independent (RGMII) signals between MAC and
PHY.
Ax pins and the control pins (DIR, OE) are referenced to V
logic levels. The devices can accept I/O voltages ranging from 1.65V to 3.6V.
There are two pinout options:
TXV0108-Q1
(8-bit direction-configurable voltage translator).
DIR pin is only available for the 8-bit device, which can be compatible with the AXC8T , AVC8T, LXC8T and
LVC8T devices depending on the application. A high on DIR allows data transmission from A to B and a low on
DIR allows data transmission from B to A when OE is set to low. When OE is set to high, both Ax and Bx pins
are in the high-impedance state. See the respective data sheets for more information.
