10.1 Layout Guidelines

The DLP801RE DMD is part of a chipset that is controlled by the DLPC4430 display controller in conjunction with the DLP300 micromirror driver and the DLPA100 power and motor driver. These guidelines are targeted at designing a PCB board with the DLP801RE DMD. The DLP801RE DMD board is a high-speed multi-layer PCB, with primarily high-speed digital logic utilizing dual edge clock rates up to 400MHz for DMD LVDS signals. The remaining traces are comprised of low speed digital LVTTL signals. Solid planes are required for DMD_P1P8V and Ground. The target impedance for the PCB is 50 Ω ±10% with the LVDS traces being 100 Ω ±10% differential. TI recommends using an 8-layer stack-up as described in Table 10-1.
