4.3 PCB Layout Recommendations

Refer to DLPC120-Q1 data sheet for specific PCB layout and routing guidelines. For specific DMD PCB guidelines, use the following:

  • VCC should have at least one 2.2-µF and four 0.1-µF capacitors evenly distributed among the thirteen VCC pins.
  • A 0.1-µF, X7R rated capacitor should be placed near every pin for the VREF, VBIAS, VRSET, and VOFF.
