Evaluation and Demonstration Boards and Kits are very important tools for engineers and scientists who are developing or researching electronic products. They provide a platform to evaluate, perform experiments, and demonstrate the capabilities of a particular electronic product.

CDCLVP1102EVM is an Evaluation and Demonstration Board marketed by Texas Instruments. This board is part of a family of display driver solutions for LCDs. It provides an easy-to-use platform for evaluating and demonstrating LCD display products containing Texas Instruments\' LVDS (Low Voltage Differential Signaling) interface.

CDCLVP1102EVM Application Field

The CDCLVP1102EVM board can be used in a variety of applications, including the evaluation and demonstration of LCD drivers for small to medium size passive LCD panels. It can be used in consumer and industrial products, such as mobile phones, TVs, tablets, and point-of-sale displays. It can also be used for the development, testing, and demonstration of applications utilizing TI\'s LVDS interface.

CDCLVP1102EVM Working Principle

The CDCLVP1102EVM is powered by a low-voltage CMOS input voltage regulator that steps down the primary supply voltage to the appropriate LVTTL voltage levels required by the TI CLC1102EVM. This generated voltage is then used to power the LVTTL buffer and logic gate circuits.

The board’s design consists of a data example eFUSE, an onboard oscilloscope header, and an unused transmitter input. The data example eFUSE is used to program the data implementation on the test board. It consists of four segments of 128 bits each, for a total of 512 bits. The oscilloscope header enables a programming cable connection to an external oscilloscope. The unused transmitter input is provided to supplement the design examples on the board in case the board’s internal eFUSE is insufficient.

The board contains several signal-specific output drivers, all of which are used to send the data to the CLC1102EVM chip. The data is transmitted from the CLC1102EVM via four output drivers. The LVDS_P pin provides a positive voltage signal, while the LVDS_N provides a negative voltage signal. The LVTTL buffer gate is used to drive the clock and data lines. Finally, the reference voltage is used to properly drive the LVDS output signal.

The test board also contains other components such as an external voltage regulator, a reference voltage source, a TI LCD display evaluation kit (EVM), and several debugging tools. The main function of the external voltage regulator is to prevent any sudden power surges or drops from damaging the CLC1102EVM. The reference voltage source is used to properly set the level of the LVDS signals, and the debugging tools help in measuring the various output signals and debugging errors during the development process.

In conclusion, the CDCLVP1102EVM is a highly useful and versatile Evaluation and Demonstration Board. It can be used for both industrial and consumer applications and is easy to program and debug. The various components on the board make it simple to evaluate and demonstrate the capabilities of the TI’s LVDS interface.
