7.3.2 Double Data Rate (DDR) Interface

Each DMD micromirror and its associated SRAM memory cell is loaded with data from the DLP controller via the DDR interface (DATA(14:0), DCLK, LOADB, SCRTL, and TRC). These signals are low voltage CMOS nominally operating at 1.8-V level to reduce power and switching noise. This high speed data input to the DMD allows for a maximum update rate of the entire micromirror array to be nearly 5 kHz, enabling the creation of seamless digital images using Pulse Width Modulation (PWM).
