TIDA-00325 Test Results
About Test Results
Test results of the TIDA-00325 reference design are performed using the DLP®
LightCrafter Display 2010 EVM which is the TI’s implementation of the TIDA-00325
reference design. This EVM incorporates the DLP 0.2" WVGA chipset comprising of the
DLP2010 DMD, DLPC3435 controller and DLPA2005 PMIC/Led Driver. The EVM and
reference design enable faster development cycles for applications requiring ultra-small
form factor optical engine and ultra-low power projection display solution. The entire test
data contained below was measured from one DLP LightCrafter Display 2010 EVM to
provide an example from a typical unit. Please note, performance will vary across EVMs
due to variations in manufacturing. The performance data is not guaranteed

LED Current Test Data
This section provides the Red, Green and Blue LED performance levels with respect to
the LED driver current levels. References are made to the DLP LightCrafter Display
Graphical User Interface (GUI) that is available for download from TI's website.
As shown in figure the LED current was increased from 100mA to 650mA in steps of
50mA and the light output at the end of the optical engine was measured using a light
measuring sphere.
The performance of the Red, Green, and Blue LEDs are shown below figures.

Throw Ratio
An optical engine’s throw ratio is defined as the ratio of the distance measured from lens
to screen and the width of the projected image.
Throw Ratio = Distance/Width
Throw ratio for the optical engine used in this ref design is 1.65

IMPORTANT NOTICE FOR TI REFERENCE DESIGNS
Texas Instruments Incorporated ("TI") reference designs are solely intended to assist designers (“Buyers”) who are developing systems that
incorporate TI semiconductor products (also referred to herein as “components”). Buyer understands and agrees that Buyer remains
responsible for using its independent analysis, evaluation and judgment in designing Buyer’s systems and products.
TI reference designs have been created using standard laboratory conditions and engineering practices. TI has not conducted any
testing other than that specifically described in the published documentation for a particular reference design. TI may make
corrections, enhancements, improvements and other changes to its reference designs.
Buyers are authorized to use TI reference designs with the TI component(s) identified in each particular reference design and to modify the
reference design in the development of their end products. HOWEVER, NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL
OR OTHERWISE TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY THIRD PARTY TECHNOLOGY

anticipate dangerous failures, monitor failures and their consequences, lessen the likelihood of dangerous failures and take appropriate
remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in
Buyer’s safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed an agreement specifically governing such use.
Only those TI components that TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components that
have not been so designated is solely at Buyer's risk, and Buyer is solely responsible for compliance with all legal and regulatory
requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
