EVM Modes
1-2
This user’s guide has been written to help you get the most from your
evaluation module (EVM). The TLC4541 EVM is a member of the
multipurpose (MP) family of serial EVMs. It provides a platform to demonstrate
the performance and functionality of the TLC4541 ADC and the
TLV5636 DAC.
TI’s websites are regularly updated. They present the latest software
additions, development information, troubleshooting help, general
background, as well as all applicable data sheets.
For specific questions related to this EVM or device send an email to the
Analog Applications Team at [email protected] and reference the
orderable tool description – TLC4541 EVM.
This user’s guide is divided into the following chapters:
- Chapter 1 offers an overview of the EVM and introduces the general
features and functions of the system.
- Chapter 2 describes the operation of the EVM from a user’s view. It details
options that can be modified, connectors used, and pinout details.
- Appendix A details the bill of materials (BOM) and the schematic, along
with explanations of certain EVM features.
1.1 EVM Modes
This EVM has been designed, tested, and shipped in a condition that enables
the user to begin evaluation with minimal effort.
There are basically two operating modes for the EVM. These modes are
mutually exclusive. They are:
- Stand-Alone Mode (SAM)
Stand-alone mode enables the user to check the system without the
support of a signal generator, pattern generator, or DSP. In this mode, the
digital output from the ADC is fed into the companion DAC and
reconstructed.
User mode is deselected if SAM is selected. The DSP will be unable to
communicate with either the ADC or the DAC.
- User Mode
The EVM typically operates via a DSP or a microprocessor. In this mode
the user is responsible for generating all the control signals. If user mode is
selected, SAM is deselected.
