3 Trace Length Matching

Trace lengths for ADC and DAC signal paths on the LPA-502 board are matched per channel as
summarized below.



Differential pair lengths are matched



ADC channel lengths are matched



DAC channels lengths are matched



ADC channels lengths do not match DAC channels lengths

~ about 1” difference

No attempt was made to adjust for any trace length differences of the Xilinx ZCU111 board.
