STAC9271/9272/9273/9274V 1.0 MARCH2007IDT CONFIDENTIAL 1.DESCRIPTION

The STAC927x (STAC9271/9272/9273/9274) family are high fidelity, 10-channel audio CODECs

compatible with the Intel High Definition (HD) Audio Interface (formerly known as “Azalia”). The

STAC927x family of CODECs provides high quality, HD Audio capability to notebook and cost sensi-

tive desktop PC applications.

The STAC927x family incorporates IDT's proprietary technology to achieve a DAC SNR up to

105dB. The higher performance and quality of IDT’s audio solutions brings consumer electronics

level performance to the notebook, desktop and media center PC.

The STAC927x family provides stereo 24- bit, full duplex resolution, supporting sample rates up to

192 KHz by the DAC and ADC. The SPDIF In/Out support sample rates of 96 KHz KHz, 48 KHz and

44.1 KHz plus SPDIF OUT supports 88.2 KHz. Additional sample rates are supported by the driver

software.

The STAC927x family supports all desired ten channel configurations, including switchable Head-

phone Out, and Universal JacksTM func?tionality for jack detection and re-tasking. The SPDIF inter-

face provides connectivity to Consumer Electronic equipment like Dolby Digital decoders, powered

speakers, mini disk drives or a home entertainment systems. All analog I/O pairs support LINE_IN,

LINE_OUT and MIC.

MIC inputs can be programmed with 0/10/20/30/40dB boost. For more advanced configurations, the

STAC927x family has up to five General Purpose I/O (GPIO) pins. The STAC927x family also pro-

vides a single ended CD input for compatibility with DRM solutions and to support leg?acy OS

issues.

The STAC927x family integrates a headphone amplifiers on Ports A, B and D. The headphone

amplifier is dedicated to these three outputs for increased flexibility, enhanced user experience, and

reduced implementation costs.

The Universal Jack? feature allows the CODECs to detect when audio devices are plugged in, and

for the CODECs to be reconfigured to support these devices regardless of which port they are

plugged into. SPDIF input sensing is also supported. The fully parametric IDT SoftEQ can be initi-

ated/disabled upon headphone jack insertion/removal for protection of notebook speakers. Note:

The Jack Detect circuit and component selection are critical for accurate detection of audio jacks on

inpidual ports. Please see the IDT STAC927x reference design for circuit implementation details.

The STAC927x family operates with a 3.3 V digital supply and a 3.3 V to 5 V analog supply.

The STAC927x family is available in a 48-pin LQFP Environmental (ROHS) packages.

STAC9271/9272/9273/9274V 1.0 MARCH2007IDT CONFIDENTIAL ESD: The STAC9271/9272/9273/9274 is an ESD (electrostatic discharge) sensitive device. The human body and

test equipment can accumulate and discharge electrostatic charges up to 4000 Volts without detection. Even though the STAC9271/9272/9273/9274 implements internal ESD protection circuitry, proper ESD precautions should

be followed to avoid damaging the functionality or performance.元器件交易网c97430dd28ea81c758f578fd

3.DETAILED DESCRIPTION 3.1.

Universal Jacks TM

IDT’s Universal Jacks TM technology allows for the greatest flexibility in board design and implemen-tation.

For the STAC927x family the Universal Jacks TM capabilities are as follows 1:?

Ports A, B, and D support 2:? Headphone Out ? Line Out ? Line In

? Mic with 0/10/20/30/40 dB Mic boost 3

?

Ports C, E, F, G, H support 2:? Line Out ? Line In

? Mic with 0/10/20/30/40 dB Mic boost 3

? Ports G & H do not have VrefOut Support

Note 1: On the STAC927x family, 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: Three Headphones should not be used simultaneously. Performance degradation will occur when using 2 Headphones simultaneously. See electrical specs for details.

Note 3: When the 40dB mic 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 MIC boost is active, the SNR, THD+N and DC offset will significantly degrade regardless of the input signal level.

3.1.1.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 port detect circuitry. Select the precision of the resistors used as follows:
