7.9 Typical Characteristics

When the DLP9000 DMD is controlled by two DLPC900 controllers, these digital controllers offer four modes of

operation.

Video Mode

Video Pattern Mode

Pre-Stored Pattern Mode

Pattern On-The-Fly Mode

In video mode, the video source is displayed on the DMD at the rate of the incoming video source.

In modes 2, 3, and 4, the pattern rates depend on the bit depth as shown in Table 1.

When the DLP9000X DMD is controlled by the DLPC910 controller, the digital controller offers streaming 1-bit

binary patterns to the DMD at speeds greater than 61 Gigabits per second (Gbps). The patterns are streamed

from a customer designed applications processor into the DLPC910 input LVDS data interface. Table 2 shows

the pattern rates for the different DMD Reset Modes.

(1)

Refer to the DLPC910 data sheet in Related Documentation for a description of the reset modes.

(2)

Pixel data rates are based on continuous streaming.

(3)

Increasing exposure periods may be necessary for a desired application but may decrease pattern rate.

(4)

Global reset mode allows for continuous or pulsed illumination source.

(5)

This reset mode typically requires pulsed illumination such as a laser or LED.
