ECNS
This section discusses the ECNs for this board. There are three (3) ECNs associated
with this board. Two are related to the alternate transceiver circuits and are discussed
in Appendix E. “Alternate Optical Transceiver Implementation”.
The last ECN relates to all transceiver circuits. Transistor Q6 was laid out with the
wrong pinout. To correct for this, transistor Q6 needs to be rotated clockwise by 1 pin.
Figure A-8 shows how to connect transistor Q6 on the PCB.
