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

... All AC-link signals are normally low through the trailing edge of RESET#. Bringing SDATA_OUT high for the rising edge of RESET# causes the AK4543 AC-link outputs to go high impedance which is suitable for ATE in circuit testing. Note that the AK4543 enters in the ATE test mode regardless SYNC is high or low. ...

... A new audio output frame begins with a low to high transition of SYNC. SYNC is synchronous to the rising edge of BIT_CLK. On the immediately following falling edge of BIT_CLK, the AK4543 samples the assertion of SYNC. This falling edge marks the time when both sides of AC-link are aware of the start of a new audio frame. On the next rising of BIT_CLK, the AC ’97 controller transitions SDATA_OUT into the first bit position of slot 0 (Valid Frame bit) ...

... The part will remain in sleep mode with all its registers holding their static values. To wake up, the AC ‘97 controller will send a pulse on the sync line issuing a warm reset. This will restart the AK4543 digital (resetting PR4 to zero). The AK4543 can also be woken up with a cold reset ...

... Regardless of the test mode, the AC ‘97 controller must issue a “Cold” reset to resume normal operation of the AC ‘97 Codec. Test Mode Functions ATE in circuit test mode When AC ‘97 is placed in the ATE test mode, its digital AC-link outputs (i.e. BIT_CLK and SDATA_IN) are driven to a high impedance state. This allows ATE in circuit testing of the AC ‘97 controller. <M0046-E-01> [AK4543] 1999/01 ...
