AD1882A
GENERAL DESCRIPTION
The AD1882A audio codec and SoundMAX® software provides
superior HD audio quality that exceeds Vista Premium performance. The AD1882A has six DACs and four ADCs, two stereo
headphone ports, C/LFE swapping, digital and analog PCBeep,
and S/PDIF output, making the AD1882A the right choice for
desktop and notebook PCs where performance is the primary
consideration.
JACK CONFIGURATION
The guidelines shown in Table 1 through Table 4 should be
used when selecting ports for particular functions.

DIGITAL MICROPHONE INTERFACE TIMING SPECIFICATIONS
The digital microphone interface can support one or two digital
microphones using two or three codec pins. Both uniplex (one
microphone per data pin) and multiplex (two microphones
sharing the same data pin) are supported. The timing for these
configurations are shown in Figure 3 and Figure 4. The interface
can generate a microphone clock at 1.5 MHz, 2.0 MHz, or
3.0 MHz to suit quality and power requirements.
