10.1 Layout Guidelines

There are no specific layout guidelines for the DMD, however the DMD is typically connected using a board to

board connector with a flex cable. The flex cable provides an interface for data and control signals between the

DLPC2607 controller and the DLP2000 DMD. For detailed layout guidelines refer to the DLPC2607 controller

layout guidelines under PCB design and DMD interface considerations.

Some layout guidelines for the flex cable interface with the DMD are:

• Minimize the number of layer changes for DMD data and control signals.

• DMD data and control lines are DDR, whereas DMD_SAC and DMD_DRC lines are single data rate.

Matching the DDR lines is more critical and should take precedence over matching single data rate lines.

• Figure 10-1 and Figure 10-2 show the top and bottom layer of the DMD flex cable connections.
