Description
HD Audio Link Serial Data Output. Codec input stream.
HD Audio Link Bit Clock Input. 24 MHz.
HD Audio Link Serial Data Input. Codec output stream.
HD Audio Link Frame Sync.
HD Audio Link Reset. Master hardware reset.
GPIO_1: General Purpose Input/Output Pin. Digital signal used for circuit control.
JS_0: Classical (DC) Jack Sense for Line_Out Pins. Low = jack not present, high = jack
present.
GPIO_0: General Purpose Input/Output Pin. Digital signal used circuit control.
JS_1: Classical (DC) Jack Sense for Headphone. Low = jack not present, high = jack
present.
Jack Sense Input for Presence Detect on Port A Through Port D. Used with isolated
switches on audio jacks.
Connect via 2.67 kΩ 1% resistor to Pin 9 (SENSE_A) when using the SENSE_A functionality.
This reduces the current draw of the jack presence tree during idle states. Remove the
resistor between Pin 9 and AV
