DLP4501FQG

Specialized ICS Overview

The DLP4501FQG is a Digital Micromirror Device (DMD) from Texas Instruments, packaged in an 80-pin CLGA format measuring 21.3 mm x 11 mm. It features a 912 x 1140 array of aluminum micromirrors with a 7.6 µm pitch, providing an effective WXGA resolution of 1280 x 800. The device operates with a clock frequency up to 120 MHz and requires specific power supplies: VCC at 2.5 V nominal, VREF at 1.8 V, VOFFSET at 8.5 V, VBIAS at 16 V, and VRESET at -10 V. Designed for side illumination, it supports a tilt angle of ±12° and functions within an operational temperature range of -20°C to 90°C.

Specialized ICS Procurement Notes

Verify that the ordering suffix FQG corresponds to the 80-CLGA package variant as specified in the datasheet. Confirm compatibility with the DLPC6401 display controller for reliable chipset operation. Ensure thermal management solutions maintain the array temperature within the recommended derating curves based on the landed duty cycle.

Specialized ICS Selection Notes

Select this component for portable applications requiring a small form factor and high-speed spatial light modulation. Ensure the optical system utilizes side illumination to match the device's design for optimal efficiency. Verify that the driving electronics support the required LVCMOS voltage levels and timing constraints for the 120 MHz maximum clock frequency.
