DLP5530PROJTGQ1EVM

User's Guide DLPU093 – November 2019 DLP5530PROJTGQ1EVM Evaluation Module User's Guide The DLP5530PROJTGQ1EVM Evaluation Module (EVM) is a complete electronic and optical subsystem designed to control and interface with the DLP5530-Q1 chipset. The DLP5530-Q1 chipset consists of the DLP5530-Q1, the DLPC230-Q1, and the TPS99000-Q1. This chipset is combined with illumination and projection optics, RGB LEDs, and a photodiode and can be used to develop an automotive grade projector for applications such as windshield cluster display and transparent window displays where a holographic optical element (HOE) is used as the screen technology. This EVM uses narrow band LED illumination designed to work more efficiently with HOE films. This projector offers high brightness and high contrast of up to 2000:1 in a compact package of about 1 liter. It is made of robust metal housing and uses all glass optical elements, but these could potentially be traded for more cost effective plastic options in a production design. The DLP5530PROJTGQ1EVM is not a production design. It is intended for evaluation only. Figure 1.

www.ti.com 1 User Guide Overview This user's guide presents an overview and general description of the DLP5530PROJTGQ1EVM and provides first steps for getting started using the EVM. 1.1 What is in the DLP5530PROJTGQ1EVM EVM The DLP5530PROJTGQ1EVM consists of a controller PCB, an illumination driver PCB, cables, and a USB to SPI adapter. It also includes an optical module designed to combine with the electronic subsystem for evaluation of a fully functioning projector in an automotive setting. 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. Figure 2.

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! Figure 3.
