AC’97 Rev 2.1 Multimedia Audio CODEC

AK4541

General Description

Features

The AK4541 is a 18bit high performance codec compliant with

Audio Codec ’97 Rev 2.1 requirements. The AC Link serial interface

allows the AK4541 to be used with digital controllers as well as

custom logic accelerators to meet PC98 and PC99 requirements for a

PCI audio solution.

• AC’97 Rev. 2.1 Compliant

• 18bit Resolution A/D and D/A

• Exceeds a PC98/99 Performance Categories:

A/D……………… 87dBA SNR

D/A……………… 87dBA SNR

D/A+Mixer…...… 85dBA SNR

A-A……………… 92dBA SNR

• Analog Inputs:

The AK4541 provides two pairs of stereo outputs with independent

volume controls along with a mono output, multiple stereo and mono

inputs, are combined to create flexible mixing, gain and mute

functions to provide a complete integrated audio solution for PCs.

4 Stereo Inputs: LINE, CD, VIDEO, AUX

Speakerphone and PC BEEP Inputs

2 Independent MIC Inputs

The AK4541 can function as a Primary AC’97 or Secondary codec

• Direct PC_Beep Pass Through for lower system costs

• Analog Output:

Stereo LINE Output with volume control

True Line Level with volume control

Mono Output with volume control

• Multiple codec Capability

The AK4541 can work as a Primary or Secondary.

• EAPD(External Amplifier Powerdown) Support

• Power Supplies:

depending on the codec ID configuration(Multiple codec extension),

making the AK4541 suitable for the docking station application and

multiple codec applications such as 4 speaker output or 6 speaker

output.

Sampling at 48kHz, the AK4541 provides excellent audio

performance. It offers extreme low power consumption, and flexible

power-down modes for use in Sub-NoteBook, laptops, desktop PCs,

and aftermarket add-in boards.

Analog 3.3V, Digital 3.3V

• Lower Power Consumption:

135mW at full operation

• 48 Pin LQFP Package

Like the earlier pin-compatible AK4540, AK4542 and AK4543, the

AK4541 is available in a compact 48-lead LQFP package.

The AK4541 is a pin compatible upgrade for the AK4540, AK4542

and AK4543, some software changes will be required to experience

the extra functions ot the AK4541.
