PRODUCTION DATA
The DLP550HE DMD is part of a chipset that is controlled by the DLPC4430 display controller in conjunction with the DLPA100 power and motor driver. These guidelines are targeted at designing a PCB board with the DLP550HE DMD. The DLP550HE DMD board is a high-speed multilayer PCB, with primarily high-speed digital logic utilizing dual edge clock rates up to ~400 MHz for DMD LVDS signals. The remaining traces are comprised of low speed digital LVTTL signals. TI recommends that mini power planes are used for VOFFSET and MBRST[0:15]. Solid planes are required for DMD_P3P3V(3.3 V) 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.
