4-CHANNEL HD AUDIO CODEC WITH QUAD DIGITAL MICROPHONE INTERFACE
STAC9204/9205
4-CHANNEL HD AUDIO CODEC WITH QUAD DIGITAL MICROPHONE INTERFACE
1.3.7.
1.3.8.
Mono Output
MONO Output is supported on pin 32 and has an independent mute and volume control. The MONO
Output derives input from the output of the summing node after DAC0. The following analog signals
feed the summing amplifier that feeds the MONO Output summing amplifier:
•
•
•
•
Universal Jacks
The Universal Jacks™ technology allows for the greatest flexibility in board design and implementa-
tion.
For the STAC9204/9205 the Universal Jacks™ capabilities are as follows
•
•
•
1.3.8.1.
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 STAC9204/9205 reference design for
port detect circuitry.
Note: MONO Output only works with the IDT Driver.
Note: 1) On the STAC9204/9205, only one function can be selected on each pin pair at a time. For
example, a pin pair cannot be configured as an input and output at the same time. Configuration
can be changed at any time.
Note: 2) Port D does not provide a microphone bias pin. Therefore only an internal, fixed-function
microphone can be supported.
Note: 3) Headphone capabilities are provided on Ports A and D, however, audio performance
degrades when 2 headphones are enabled.
Note: 4) When the 40dB microphone boost feature is enabled, additional gain increases greater
than 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.
DAC0 Output: When enabled, both DAC0 Outputs are summed together.
Analog PC Beep: Sourced from pin 12.
ADC Input: Stereo analog feed into the stereo ADC input.
The combination of the stereo channels from DAC0 are combined into a single analog signal
with a -6dB degradation in signal strength.
