Description
Link Serial Data Output. AD1883 input stream. Clocked on both edges of the
BIT_CLK.
Link Bit Clock. 24.000 MHz serial data clock.
Link Serial Data Input. AD1883 output stream clocked only on one edge of BIT_CLK.
Link Frame Sync.
Link Reset. AD1883 master hardware reset.
Digital microphone 1 and 2 Inputs (for Biphase Microphones), or Digital Microphone
1 Input (for Single-phase Microphones).
Digital Microphone 2 Input (for Single-phase Microphones).
Clock to Drive External Digital Microphones.
General-Purpose Input/Output Pins. Digital signals used to control or sense external
circuitry.
Microphone Bias for Port E/General-Purpose Input/Output. Capable of high-Z, 1.65 V,
and 2.86 V. Pin 31 shares functionality between MIC_BIAS_E (default) and GPIO_1.
These functions are mutually exclusive and the MIC_BIAS function takes priority over
the GPIO function.
EAPD/General-Purpose Input/Output Pin. Pin 47 shares functionality between
GPIO_0 and EAPD. These functions are mutually exclusive and the EAPD function
takes priority over the GPIO function. By default, the pin is in a high-Z state. External
resistors should be used to ensure the proper circuit state when this pin is in high-Z.
Supports S/PDIF Output.
Jack Sense A-D Input/Sense B drive.
Jack Sense E-F Input/Sense A drive.
Monaural Input from System for Analog PCBeep.
Auxiliary Input/Output Left Channel.
Auxiliary Input/Output Right Channel.

Auxiliary Input/Output Right Channel.
CD Audio Analog Ground Reference. Must be connected to AGND via a 0.1 μF
capacitor if not in use as CD_GND. MUST always be ac-coupled.
