MityDSP-L138F LVDS lengths? .... (posted on behalf of a customer)

Added by Angela Newman over 8 years ago

My company is using your MityDSP-L138F SoM in a research prototype. The design has a high speed LVDS bus to the Spartan-6. We need to design LVDS bus with an off module clock input connecting to the FPGA O-SERDES2. To clculate the clock skew at the LVDS receiver on our board we need the total trace lengths including the tarces on the SoM. If it's possible please provide the trace lengths of the following pairs

144,146 B0_24
148,150 B0_22
153,155 B0_19
157,159 B0_17
161,163 B0_15
166,168 B0_14
165,167 B0_13
169,171 B0_11
175,177 B0_9
179,181 B0_7
176,178 B0.10
