Dennis Field / dvk-mx8m-bsb - History

In preperation for the final order, re-export all the manufacturing files using the current date and rev number v1.0.0

Add the fab's stackup, panel array working files, and their CPW calculations

Bring the HDMI diff pair shield pins directly to GND instead of the 0Ohm resistor which goes to GND

Increment the version number for any new changes/fixes which are made (v0.1.3)

Make the ENET_* traces on the top layer 53mils in order to ensure they have a 50Ohm single-ended impedence, move one of the 5V_P bypass caps close to the SoM end of the USB2 diff pair, add meanders to the ENET_TXC, ENET_TX_CTL, ENET_RX_CTL in order to ensure these segments are matched to the long ENET_RXC segment (56.051mm, the rest of the RGMII signals are <10mm skew from this length and don't need adjusting, re-route the SIM card such that UIM-RESET is routed in between UIM-CLK and UIM-DATA as recommended by a BB manufacturer

Add pi-matching circuit to the baseband modem antenna's feedline

The return path for the antenna may have to have a 6.8nH Murata LQG15HN inductor installed on it (cutting the ground trace shorting the pads). The BoM was updated with the new components and everything was reannotated and updated (page 2's caps were out of order).

Complete the HDMI circuit routing (including the pull-down NFETs and the diff pairs going to them)

The diff pairs going to the NFETs are exactly matched to 0 with their phase/skew; 1V8P still needs to be brought to them.

Change all 0603 capacitors _EXCEPT_ the 2.2uF, 4.7uF, 8.2uF, 10uF, and 22uF caps to 0402

Add new built-in mic's frequency response curve to the schematic and re-simulate the HP_DET pin circuit with the protection diode's SPICE model included

Replace the CMC-6022-37T microphoen with the CMC-2242PBL-A THT one since the old one cannot be surface mounted/reflowed, add the microphone's 3D model

The microphone's pin position/order is agrees with the manufacturer's "measurement circuit" from the datasheet such that the right (facing the top of the mic) terminal/pin is its GND (-).
