JAJSI71C April 2019 – February 2023 DLP470NE
PRODUCTION DATA
The DLP470NE DMD is part of a chipset controlled by the DLPC4430 display controller in conjunction with the DLPA100 power and motor driver. These guidelines help to design a PCB board with the DLP470NE DMD. The DLP470NE DMD board is a high-speed multilayer PCB, with primarily high-speed digital logic using 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, VRESET, and VBIAS. Solid planes are required for DMD_P3P3V(3.3 V), 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.
