DMD Interface Considerations

The sub-LVDS HS interface waveform quality and timing on the DLPC3434 ASIC is dependent 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.

As an example, DMD interface system timing margin can be calculated as follows:

Equation 1. Setup Margin = (DLPC3434 output setup) – (DMD input setup) – (PCB routing mismatch) – (PCB SI degradation)
Equation 2. Hold-time Margin = (DLPC3434 output hold) – (DMD input hold) – (PCB routing mismatch) – (PCB SI degradation)

where

    DLPC3434 I/O timing parameters as well as DMD I/O timing parameters can be found in their corresponding data sheets. Similarly, PCB routing mismatch can be budgeted and met through controlled PCB routing. However, PCB SI degradation is a more complicated adjustment.

    In an attempt to minimize the signal integrity analysis that would otherwise be required, the following PCB design guidelines are provided as a reference of an interconnect system that will satisfy both waveform quality and timing requirements (accounting for both PCB routing mismatch and PCB SI degradation). Variation from these recommendations may also work, but should be confirmed with PCB signal integrity analysis or lab measurements.
