J7EXPA01EVM Evaluation Module
Description
The J7EXPA01EVM add-on board is designed to
expand the capability of Jacinto7 EVMs to include
video capture capabilities. This hardware system can
help kick start the development and evaluation of
the Jacinto7 family of processors in many different
automotive and industrial applications.
The J7EXPA01EVM provides the ability to interface
with external camera sensors, radar sensors,
and other similar capture devices through Texas
Instruments FPD-Link serial links. The EVM
can support up to twelve different inputs, and
communicates with the processor through multiple
MIPI D-PHY CSI2 interfaces.

    1 Evaluation Module Overview 1.1 Introduction The J7EXPA01EVM is an expansion and add-on module and does not operate stand-alone. The EVM is designed to be matched with Jacinto7 Processor EVMs, including J721EXCPXEVM and J784S4XEVM. Other hardware configurations can be supported but are not covered in this document. This design is not a reference design, as the design includes circuitry for software development, debug, and flexible configurations.

    2 Hardware 2.1 Key Features and Interfaces The J7EXPA01EVM is a add-on module that expands the feature set of select TI processor evaluation modules (EVMs) to include advanced video capture features. The combined EVM design provides users the ability to evaluate and develop automotive and industrial applications that utilize advanced video and image processing.
  • Page 4 Figure 2-2. Key Features and Interfaces (Bottom) 2.2 EVM Compatibility The J7EXPA01EVM is not a stand-alone EVM but is an add-on or expansion board that must be combined with a base EVM. Table 2-1 includes several Texas Instruments EVMs that can support the J7EXPA01EVM. This list is not meant to be all inclusive and the J7EXPA01EVM can be supported with other EVM systems.
  • Page 5 The base EVM does provide power to the J7EXPA01EVM add-on module and is sufficient to cover basic power needs. If the attached sensors require have more substantial power requirements, then users have to supplement the EVM and, specifically, the J7EXPA01EVM requires additional power input.
