Audio Jack Presence Detect
SPDIF Output
SENSE_A pin is used to detect the presence of plugs in ports A, B, C, and D. SENSE_B pin is used
to detect the presence of plugs in ports E and F. Refer to the reference design for port detect cir-
cuitry. Select the precision of the resistor used as follows.
SPDIF Output can operate at 44.1 KHz, 48 KHz and 96 KHz, as defined in the Intel High Definition
Audio Specification, with resolutions up to 24 bits. This insures compatibility with all consumer audio
gear and allows for convenient integration into home theater systems and media center PCs.
