1.4.1 Audio Inputs

1.4.1.1 Analog Line-level Inputs (J3)

Analog line-level inputs have the following characteristics:

•

Connector Type: High-Density High-Speed Shrouded Female Connector

•

Absolute Maximum Signal Level: These signals should only be driven from the connectors on the
main board. Voltages should comply with the Max Signal Level specification for the main board
circuitry.

1.4.1.2 Digital Audio Inputs (DAI) (J2)

The DAI connector has the following characteristics:

•

Connector Type: High-Density High-Speed Shrouded Female Connector

•

Absolute Maximum Signal Level: +3.6V

•

Absolute Minimum Signal Level: -0.3V

This connector passes all serial audio data and clock signals up from the main CDB47xxx board.
