GENERAL DESCRIPTION

www.BDTIC.com/ADI
The AD1883 audio codec and SoundMAX® software provide superior high definition audio quality that exceeds Vista Pre­mium performance for notebooks. The AD1883 has two 192 kHz DAC pairs, two 192 kHz ADC pairs, a S/PDIF output, a 2-channel digital microphone interface, and digital and analog PCBeep. These features make the AD1883 the right choice for notebook PCs that meet Microsoft Vista Premium performance as well as desktop PCs that meet Microsoft Vista Basic performance.
The AD1883 is available in a 48-lead, RoHS compliant lead frame chip scale package in both reels and trays. See Ordering
Guide on Page 19.

ADDITIONAL INFORMATION

This data sheet provides a general overview of the AD1883 SoundMAX codec’s architecture and functionality. Detailed widget information is available in the AD1883 Programmers Reference Manual. Please contact your local Analog Devices, Inc., sales representative for more information.

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 is shown in Table 6 and Figure 3, Figure 4 and
Figure 5. The interface can generate a microphone clock at
1.5 MHz, 2.0 MHz, or 3.0 MHz to suit quality and power requirements.
