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

allows the AK4543 to be used with digital controllers as well as

custom logic accelerators to meet full PC98 and PC99 requirements

for a PCI audio solution.

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.

The AK4543 can function as a Primary AC’97 or Secondary codec

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

making the AK4543 suitable for the docking station application and

multiple codec applications such as 4 speaker output or 6 speaker

output.

Sampling at 48kHz, the AK4543 provides excellent audio

performance, meeting or exceeding all standard requirements. It

offers low power consumption, and flexible power-down modes for

use in laptops, desktop PCs, and aftermarket add-in boards.

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

is available in a compact 48-lead LQFP package.

The AK4543 is a pin compatible upgrade for the AK4540 and

AK4542, some software changes will be required to experience the

extra functions ot the AK4543.

The AK4543 is a 18bit high performance codec compliant with

The AK4543 provides two pairs of stereo outputs with independent
