7.3.9.1 Sub-LVDS (HS) Interface

The DLPC3439 controller to DMD interface consists of a HS 1.8-V sub-LVDS output only interface with a maximum clock speed of 532-MHz DDR and a LS SDR (1.8-V LVCMOS) interface with a fixed clock speed of 120 MHz.Table 7-9 shows the two options available for the DLP4710 DMD.

Figure 7-15 DLP4710 (.47 1080p) DMD Interface

The sub-LVDS high-speed interface waveform quality and timing on the DLPC34xx 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.
