7.3.9.1 Sub-LVDS (HS) Interface

The DLP230NP/NPSE (.23 Full HD) DMD does not require all of the available output data lanes of the controller. Internal software selection allows the controller to support multiple DMD interface swap configurations. These options can improve board layout by remapping specific combinations of DMD interface lines to other DMD interface lines as needed. Table 7-8 shows the two options available for the DLP230NP (.23 Full HD) DMD specifically.

The sub-LVDS high-speed interface waveform quality and timing on the DLPC34x6 controller depends on the total length of the interconnect system, the spacing between traces, the characteristic impedance, etch losses, and how well matched the lengths are across the interface. Thus, ensuring positive timing margin requires attention to many factors.

In an attempt to minimize the signal integrity analysis that would otherwise be required, the DMD Control and Sub-LVDS Signals layout section is provided as a reference of an interconnect system that satisfy both waveform quality and timing requirements (accounting for both PCB routing mismatch and PCB signal integrity). Variation from these recommendations may also work, but should be confirmed with PCB signal integrity analysis or lab measurements.
