Other Parts Discussed in Thread: DLPC900
Hi,
I am designing two boards, one which uses two DLPC900s, and another with the DLP9000. I have routed the differential pair tracks for length, width, spacing, etc. as indicated in the DLPC900 spec. But for the single-ended signals, I see very little in terms of recommendations. Specifically for the DAD* signals:
1) Is there a maximum length requirement?
2) For my calculations, shall I assume that these are 200MHz signals? Are they something less than that?
3) Do these signals need to be length-matched with each other?
4) Spec says 50Ohm impedance, but some signals have a 470Ohm termination on the DMD side. What is that for?
Thanks,
Hanson
