DLP480REFXG

Specialized ICS Overview

The DLP480REFXG is a digital micromirror device (DMD) from Texas Instruments, featuring a 0.48-inch diagonal micromirror array with WUXGA resolution (1920 × 1200). It utilizes a 5.4-micron pitch and ±17° tilt angle for spatial light modulation. The component operates on a 1.8 V LVCMOS core supply (VCC) and requires specific high-voltage supplies: VOFFSET at 10 V nominal, VBIAS at 18 V nominal, and VRESET at -14 V nominal. It accepts two LVDS input data buses with a maximum clock frequency of 400 MHz. The device is housed in a 257-pin BCLGA package.

• Serial Communications Port (SCP) for configuration and control

Specialized ICS Applications

• WUXGA display systems
• Smart displays
• Digital signage
• Business projectors
• Education projectors

Specialized ICS Procurement Notes

Verify the FXG suffix corresponds to the 257-pin BCLGA package variant. Confirm that the system design includes the required DLPC4422 controller and DLPA100 power management IC, as the DMD relies on these chipset components for reliable operation. Ensure PCB layout adheres to TI's design guidelines for signal trace lengths and impedance matching.

Specialized ICS Selection Notes

Select this component for applications requiring 0.48-inch WUXGA form factors. Ensure the optical system limits the marginal ray angle to 55 degrees to prevent thermal degradation. Verify that the cooling solution can maintain the array temperature within the long-term operational range of 10°C to 70°C based on the duty cycle derating curve.

Specialized ICS Part Context

The DLP480RE is part of the DLP 0.48-inch WUXGA chipset family. It is designed to work in conjunction with the DLPC4422 display controller and DLPA100 power and motor driver. This combination provides a cost-effective, high-resolution display solution for various projection and direct-view applications.

Specialized ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Replacement should involve verifying compatibility with the existing DLPC4422 and DLPA100 chipset architecture.
