Dennis Field / dvk-mx8m-bsb - History

Continue with the audio CODEC schematic, selected a potential STIA 3.5mm headphone jack, use logic level shifters on the WWAN/BT M.2's UART and PCM interfaces since the M.2 spec states that these are 1.8V logic levels

Still need to assign the corresponding SAI interface for the BT.

Include RJ45 connector selection information (likely using JD1-0001NL)

Add ethernet PHY schematic, assign the RGMII signals, and include its associated 48-QFN footprint

Assign verious signals such as W_DISABLE1, W_DISABLE2, WWAN_DISABLE; reorder the hierarchy to make more sense; add "solid" graphic lines around the power signals on the top sheet for clarity

Organize the USB-C, Battery, and Power sheets at the top-level such that the power-flow makes more sense when reading the schematic

Add I2C interface to WiFi/BT M.2, select an appropriate dual 2-input AND gate IC for the W_DISABLE logic and add the corresponding debounce/pull-down circuit to the HKS for W_DISABLE

Notes have been included regarding the I2C logic level voltage. If the USB interface is used then the input voltage needs to be 5.0V (not 3.3V); therefore the USB interface and hub may need to be removed!

Several signals are unused by the RS9116 WiFi/BT module, as noted in the schematic.

Footprints of SD card socket and demultiplexer assigned

Add demultiplexer to uSDHC2 for the uSD and WiFi's SDIO interfaces, include the DEMUX's (TS3A27518E) 24QFN footprint

Bring back the *-cache.lib file as it is a very important in case someone opens the schematic and is missing any of the symbols used

Add MicroSD footprint from selection, add PDF file with searchable/highlightable text
