DLP5530Q1EVM Evaluation Module User's Guide

The DLP5530Q1EVM Evaluation Module (EVM) is a complete electronic subsystem designed to control

the DLP5530-Q1 chipset. The DLP5530-Q1 chipset consists of the DLP5530-Q1, the DLPC230-Q1, and

the TPS99000-Q1. When combined with illumination and projection optics, RGB LEDs and a photodiode,

this EVM can be used to develop an automotive grade projector for applications such as augmented

reality head-up display (AR HUD) or interior projection systems.

Except for the DMD, there are no optical elements provided with this EVM. It is expected that this EVM is

procured in order to mount to a custom designed picture generation unit (PGU) or projector.

The DLP5530Q1EVM is not a production design. It is intended for evaluation only.

The DLP5530Q1EVM electronics EVM pairs with 3 different optical module configurations, all available as

standalone EVMs. The different options are listed below in Table 1.

1 User Guide Overview

This user's guide presents an overview and general description of the DLP5530Q1EVM and provides first

steps for getting started using the EVM.

1.1 What is in the DLP5530Q1EVM EVM

The DLP5530Q1EVM consists of a controller PCB, an illumination driver PCB, cables, and a USB to SPI

adapter.

1.1.1 Controller PCB

The controller PCB shown in Figure 2 includes the DLP5530-Q1 DMD, the DLPC230-Q1 DMD Controller,

and the TPS99000-Q1. It supports video inputs from either a micro HDMI or OpenLDI interface and

provides the formatting and control to display the video on the DLP5530-Q1 DMD. The EVM can be

controlled with either a SPI or an I2C interface. The SPI or I2C interface can also be used to reprogram the

serial Flash that is used to store DLPC230-Q1 software and configuration. An optional second SPI port is

provided for monitoring the TPS99000-Q1. The EVM has an external photodiode input that is used to

control white point and brightness over a wide dimming range. An optional second photodiode input is also

provided. The EVM includes a flex interface to control and monitor the illumination driver PCB. It also

provides an optional interface for thermistors on the red, green and blue illuminator PCBs that can be

used to monitor the temperatures of the illuminators.

The controller PCB contains the ports listed in Table 2. Indicator LEDs are listed in Table 3.

turn on and off the electronics. Note that parts of the board are still powered when PROJ_ON is in the off

position. SW1, SW2 and SW3 are dip switches that control the states of configuration signals the

DLPC230-Q1 reads when it comes out of reset. These switches should be set based on the desired

configuration options.

1.1.2 Illumination Driver PCB

The illumination driver PCB shown in Figure 3 is controlled and monitored by the controller PCB over a

flex cable. Power can be input to the illumination driver from a bench top supply. The illumination driver

provides reverse bias protection and supplies power to the controller PCB over a separate cable. The

illumination driver PCB regulates the input power to 6.5 V or 8 V prior to the illumination driver circuitry.

The illumination driver has outputs for red, green and blue illuminators. These are typically LEDs, but it is

possible other illuminators could be used. See Section 1.2.1 for input and output specifications of the

EVM. Depending on operating conditions, some parts and surfaces of the PCB can be hot.

CAUTION

Hot surface. Contact may cause burns. Do not touch!

The illumination driver PCB contains the ports listed in Table 5.
