DLPS013H April 2010 – December 2024 DLP5500
PRODUCTION DATA
When designing a PCB board for the DLP5500 controlled by the DLPC200 in conjunction with the DLPA200, the following are recommended:
Signal trace corners should be 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.
High-speed signal traces should not cross over slots in adjacent power and ground planes.
Signal | Constraints |
---|---|
LVDS (DMD_DAT_xnn, DMD_DCKL_xn, and DMD_SCTRL_xn) | P-to-N data, clock, and SCTRL: <10mil (0.25mm); Pair-to-pair
<10mil (0.25mm); Bundle-to-bundle <2000mil (50mm, for example
DMD_DAT_Ann to DMD_DAT_Bnn). All matching should include internal trace lengths. See Section 5 for internal package trace lengths. Trace width: 4mil (0.1mm) Trace spacing: In ball field – 4mil (0.11mm); PCB etch – 14mil (0.36mm) Maximum recommended trace length <6 inches (150mm) |
Signal Name | Minimum Trace Width | Minimum Trace Spacing | Layout Requirements |
---|---|---|---|
GND | Maximize | 5mil (0.13mm) | Maximize trace width to connecting pin as a minimum |
VCC, VCC2 | 20mil (0.51mm) | 10mil (0.25mm) | |
MBRST[15:0] | 10mil (0.25mm) | 10mil (0.25mm) |
