DLPU077–March 2019

DLPDLCR660TEVM and DLPLCRDC4422EVM Overview

1.1 Welcome

The DLP Products DLPDLCR660TEVM and DLPLCRDC4422EVM evaluation modules (EVMs) offer a

reference design to enable faster development cycles for users of the DLPC4422 chips and allow

evaluation of TI’s DLP660TE UHD chipset.

These evaluation kits bring together a set of components providing a great starting point to evaluate a

UHD DLP system for:

• Laser TV

• Enterprise Projectors

• Digital Signage

• Gaming Machines

• Smart Projectors

• State Lighting Systems

1.2 What is in the DLPDLCR660TEVM and DLPLCRDC4422EVM Evaluation Modules (EVMs)?

The DLPDLCR660TEVM and DLPLCRDC4422EVM are designed to be used together. In fact, one cannot

be operated without the other.

The DLPDLCR660TEVM, which includes the DLP660TE display chip, includes the two flex cables

required to connect the DLPDLCR660TEVM to the DLPLCRDC4422EVM. DLPLCRDC4422EVM includes

all circuitry required to drive the DLP660TE display chip.

The DLPLCRDC4422EVM, which includes two DLPC4422 controllers in master-slave mode, two

DLPA100s which serve as the power management and motor drivers, and other system circuitry such as

the Vx1 receiver and system fan control.

The DLPLCRDC4422EVM can be programmed with the DLP660TE firmware which is available on the

DLPC4422 product page. This firmware allows the DLPLCRDC4422EVM to drive the DLP660TE chip.

Figure 1-1 and Figure 1-2 show the top side of each EVM.

NOTE: Figure 1-2 does not show the necessary flex cables needed to pair to DLPLCRDC4422EVM.

DLPDLCR660TEVM and DLPLCRDC4422EVM Overview

1.3 EVM Boards

The DLPDLCR660TEVM and DLPDLCRDC4422EVM contain the electronics required to drive the

DLP660TE DMD. The DLPLCRDC4422EVM offers several interface options for USB, I2C, and trigger

inputs and outputs.

The system block diagram Figure 1-3 details the functionality and control when using the

DLPDLCR660TEVM and DLPDLCRDC4422EVM.

Figure 1-3. EVM System Block Diagram

The major components of the DLPLCRDC4422EVM are:

• Two DLPC4422 controllers

• Two DLPA100 power management and motor driver chips

• Altera FPGA used to split incoming Vx1 data for the two DLPC4422 controllers

The major components of the DLPDLCR660TEVM are:

• DLP660TE 0.66-inch UHD DMD

• Two flex cables designed to connect the DLPDLCR660TEVM to the DLPLCRDC4422EVM

• TPS65145 used to generate the DMD's reset voltages

1.4 Other Items Needed for Operation

The DLPDLCR660TEVM and the DLPLCRDC4422EVM are evaluation modules (EVM) that are capable of

displaying images on to the DMD. However, these EVMs do not ship with optics, illumination source,

cables, power supplies, or additional hardware components. These are system parameters that are left for

the user to design, the EVMs are meant to accelerate initial system design.

• Power supply (See Section 4.1)

• Mini-USB cable: A to B USB cable

• Optics

• Illumination module and source

• Front-End Vx1 Source capable of running at 600 MHz pixel clock

DLPLCRDC4422EVM and DLPDLCR660TEVM EVM Flex Cable

DLPU077–March 2019

DLPDLCR660TEVM and DLPLCRDC4422EVM Overview

1.5 DLPLCRDC4422EVM and DLPDLCR660TEVM EVM Flex Cable

Electrical malfunctions can occur by stressing the flex cable(s) connecting the DMD circuit board to the

DLPLCRDC4422EVM controller circuit board. Stressing the flex cable can be caused by:

• Bending the cable outside the area identified in Figure 1-4 (within 20.3 mm of connector plate centers).

• Repeatedly bending the flex cable(s) where the bend radius is less than 25.4 mm.

• A single bending of the flex cable(s) where the bend radius is less than 6.35 mm.

Figure 1-4. Flex Cable Diagram

NOTE: The minimum bend radius for forming flex cable (flexible) circuit is 6.35 mm

Minimize any handline/movement on the flex cables during operation

Use caution when bending the flex cable to not exceed bending guidelines explained above.

Quick Start

Chapter 2

DLPU077–March 2019

Quick Start

This chapter offers a quick start guide on how to connect the DLPDLCR660TEVM to the

DLPLCRDC4422EVM, how to power up the DLPLCRDC4422EVM, and how to program the

DLPLCRDC4422EVM to display a SPLASH image on the DMD.

2.1 Downloading the Software

Before programming the DLPLCRDC4422EVM, ensure the DLPC4422 GUI and DMD firmware are both

downloaded on the PC. The DLPC4422 GUI will allow for operation of the EVM and the DMD firmware is

required so the DLPLCRDC4422EVM knows which DMD is being controlled. If the DLPDLCR660TEVM is

being used with the DLPLCRDC4422EVM, the DLP660TE firmware is needed.

The DLP660TE firmware and DLPC4422 GUI can be found under the “Tools and Software” tab on the

product pages on TI.com. This is the product page for the DLP660TE and the product page for the

DLPC4422.

2.2 Connecting the DLPDLCR660TEVM to the DLPLCRDC4422EVM

Before connecting the DLPDLCR660TEVM to the DLPLCRDC4422EVM, locate the two flex cables that

are packaged with the DLPDLCR660TEVM. Ensure the flex cables are not torn or damaged before

connecting the DLPDLCR660TEVM or the DLPLCRDC4422EVM.

The flex cables are exactly the same, meaning there is not a “right” or “left” cable. The cables are

interchangeable, as long as the side of each cable labeled “DMD END” is connected to the

DLPDLCR660TEVM and the other end is connected to the DLPLCRDC4422EVM.

The steps for the connecting the EVMs are listed below:

1. Unscrew and remove the backer plate on each end of the flex cable.

2. Position the flex cable end which says “DMD END” to the backside of the DMD board.

3. Insert the two guide pins of the flex cable into the DMD board.

4. Using the guide pins, place one backer plate on the front side of the DMD board.

5. Screw the flex cable screws clockwise into the backer plate until nearly fully inserted

6. Take turns screwing in the screws so until each is lightly snug. Do not over-tighten.
