PCB Signal Routing

When designing a PCB board for the DLPC200 the following are recommended:

Maintain signal trace corners no sharper than 45°. Adjacent signal layers should have the predominate traces routed orthogonal to each other. TI recommends that critical signals be hand routed in the following order: DDR2 Memory, DMD (LVDS signals), then DLPA200 signals.

TI does not recommend signal routing on power or ground planes.

TI does not recommend ground plane slots.

Do not allow high speed signal traces to cross over slots in adjacent power and/or ground planes.

Table 10. Important Signal Trace Constraints

Signal Constraints
DDR2 differential clock pairs P-to-N length <12 mils (0.31 mm)
Trace width: 30 mil (0.76 mm)
DDR2 data Length within ±150 mils (3.81 mm) relative to DDR2 differential clock
Maximum termination signal recommended trace length <0.5 inch (12.7 mm)
LVDS (DMD_DAT_xnn,
DMD_DCKL_xn, and DMD_SCTRL_xn)
P-to-N data, clock, and SCTRL: <10 mils (0.25 mm); Pair-to-pair <10 mils (0.25 mm); Bundle-to-bundle <2000 mils (50 mm, for example DMD_DAT_Ann to DMD_DAT_Bnn)
Trace width: 4 mil (0.1 mm)
Trace spacing: In ball field – 4 mil (0.11 mm); PCB etch – 14 mil (0.36 mm)
Maximum recommended trace length <6 inches (150 mm)

Table 11. Power Trace Widths and Spacing
