Ac97 Multimedia Audio Codec With Src

The AK4544A is a 18bit high performance codec which support variable sampling rate conversion compliant with Audio CODEC 97 Rev 2.1 requirements. The AK4544A provides two pairs of stereo outputs with independent Volume Controls a mono output, and multiple stereo and mono inputs, along with flexible mixing, gain and mute functions to provide a complete integrated Audio solution for PCs. In addition, the AK4544A has the POP feature suitable for 3D positioning and direct output from DAC for AD monitoring or docking station application. The AK4544A CAN function as a Primary AC 97 or Secondary codec depending on the codec ID configuration(Multiple codec extension), making the AK4544A suitable for the docking station application and multiple codec applications. Sampling frequency is programmable through AC-link as 48k, 44.1k, 32k, 22.05k, 16k, 11.025k, and 8kHz. This setting is done independent to ADC and DAC side while L/R channels are kept identical. The AK4544A provides excellent Audio performance, meeting or exceeding PC99 requirements for a PCI Audio solution. It has low power consumption, and flexible power-down modes for use in laptops as well as desktop PCs and aftermarket add-in boards. Like the earlier pin-compatible AK4540, AK4541 AK4542, and AK4543, the AK4544A is available in a compact 48-lead LQFP package. Reference : Audio CODEC 97 Revision 2.1 By AKM Semiconductor, Inc.
