6.9 Audio

The 96Boards CE specification calls for a minimum of single channel audio through two interfaces either via Bluetooth 4.0 or audio

output at HDMI/MHL/Display Port.

96Boards also requires I2S/PCM audio channel to be provided on the low speed expansion interface.

The SD 600eval board meets this requirement. For additional audio functionality, APQ8064 is interfaced with audio codec

WCD9310 via SLIMBUS. WCD9310 provide 6 analog differential mics, 2 digital mics, 5 speaker outs and one headset (headphone

out and single ended mic input) signals, routed to Audio Expansion connector (J4 & J6). The details of connector J4 & J6 are

mentioned in section 7.3 Audio Expansion Connector

The 96Boards CE specification calls for power to be provided to the board in one of the following ways:

•

An 8V to 18V power from a dedicated DC jack

•

An 8V to 18V power from the SYS_DCIN pins on the Low Speed Expansion Connector

•

A USB Type C port at 5V (not supported on SD 600eval Board)

The SD 600eval board exceeds the power input requirement and can operate from as low as 6.5V power input.

Please see section 8.2 for detailed information on SD 600eval implementation of DC Power.

The 96Boards CE specification calls for support for measuring power consumptions of the board. Please see section 8.4 for
