8-CHANNEL HIGH DEFINITION AUDIO CODEC

8-CHANNEL HIGH DEFINITION AUDIO CODEC
Universal Jacks
3.1.1.
IDT’s Universal Jacks technology allows for the greatest flexibility in board design and implementa-
tion.
For the 92HD206 family the Universal Jacks capabilities are as follows
•
•
Note
example, a pin pair cannot be configured as an input and output at the same time. Configuration can
be changed at any time.
Note
when using two headphones simultaneously. See electrical specs for details.
Note
6dB may result in significant audio quality degradation of the microphone audio input. In particular,
when the 40dB microphone boost is active, the SNR, THD+N and DC offset will significantly degrade
regardless of the input signal level.
Audio Jack Presence Detect
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, F, G, ad H. Refer to the reference design for details of the
port detect circuitry.
Impedance Sense is accomplished by on-chip circuitry that measures the impedance at the pin of
the chip and compares it to internal reference impedance bins. Below, is a table that contains the bin
information and codes returned when the pin widget impedance field in the Port Pin Sense widget is
read. Please note that even under the best conditions, there is no method to guarantee 100%
impedance sensing due to variations in external circuitry and impedance overlap of devices that can
be plugged into a jack. The impedance sense table reflects both standard Line Out and Headphone
output drivers. Please reference the HD Audio Universal Jack Application Note on the IDT Extranet
for more information.
