DLP3940SQ1EVM
DLP3940S-Q1 evaluation module
DLP3940SQ1EVM
Overview
The DLP3940SQ1 evaluation module (EVM) is a complete electronic subsystem designed to control the DLP3940S-Q1, DLPC231S-Q1, and TPS99002SQ1 devices, which support RGB display applications such as augmented reality head-up displays. There are no optical elements provided with this EVM, except for the DMD. Expect that this EVM is procured to mount to a custom-designed picture generation unit (PGU) or projector.
Features
- DLP3940S-Q1 DMD board with RGB display LED driver and DLPC231S-Q1 DMD controller for DLP3940SQ1EVM kit
- 600MHz SubLVDS DMD interface for low power and emission
- DMDs have 0.39-inch diagonal micromirror array
- 4.5µm micromirror pitch
- ±14.5° micromirror tilt angle
- Side illumination enables high efficiency and smaller engine size
- 10kHz DMD refresh rates over temperature extremes
- Compatible with LED illumination
- Video input interface on controller board
- Single OpenLDI (FPD-Link™ I) port up to 110MHz
- 24-bit RGB parallel interface up to 110MHz
- Configurable host interface
- Inter-Integrated Circuit (I2C) (400kHz)
- Serial Peripheral Interface (SPI) (10MHz)
