7. ADDENDUM
There are three hardware modifications to the circuit board as follows:
1) U16 pin 10 and U16 pin 13 are unterminated in the schematic set. They should have been connected to ground.
2) U17 pin 11 is grounded in the schematic set. It should have been left unterminated. A top side modification was
3) The MCLK_TO_DSP- signal trace between U29 pin 1 and U47 pin 1 got merged to the ground fill beneath the
36
A top side modification was performed on the board by adding a wire from U16 pin 10 to U16 pin 13, then to the
ground pad at C94.
performed by lifting U17 pin 11.
crystal oscillator Y1. A top side modification was performed on the board by cutting the trace to disconnect it
from the ground fill. A bottom side modification was performed on the board by adding a wire to reconnect the
trace.
