SPDIF Ouput can operate at 44.1 KHz, 48 KHz, 88.2 KHz and 96 KHz, as defined in the Intel High
Definition Audio Specification, with resolutions up to 24 bits. This insures compatibility with all con-
sumer audio gear and allows for convenient integration into home theater systems and media center
PCs.

interface for up to 8 channels of uncompressed 24-bit data. Sample rates up to 192 KHz are sup-
ported for 2 channels, up to 96 KHz for 4 channels, or up to 48 KHz for 8 channels.
The digital microphone interface permits connection of a digital microphone(s) to the STAC9274 via
the DMIC0, DMIC1, and DMIC_CLK 3-pin interface. The DMIC0 and DMIC1 signals are inputs that
carry individual channels of digital Mic data to the codec. In the event that a single microphone is
used, the data is routed to both ADC channels.
The DMIC_CLK output is programmable from 1.176 MHz to 4.704 MHz in 1.176 MHz increments
and is synchronous to the 24 MHz internal clock. The default frequency is 2.352 MHz.
The STAC9274 supports the digital microphone configurations described in Tables 3 and 4, and
shown in Figures 1, 2 and 3, below.
Note: Some Digital Microphone implementations support data on either edge, therefore, an
external mux may not be required.
