General Description
The AK4543 is a 18bit high performance codec compliant with
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.
The AK4543 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.
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.
