Cirrus Logic's WM8804 and WM8805 are digital interface transceivers designed specifically for S/PDIF (IEC60958-3) data recovery, routing, and transfer. These integrated circuits (ICs) offer high-performance solutions for audio applications.
One key feature of the WM8804/WM8805 is their advanced jitter attenuating PLL (Phase-Locked Loop). Jitter refers to the unwanted variations in the timing of digital signals, which can cause distortion and other issues in audio transmission. The PLL in these ICs helps to mitigate this problem by reducing the impact of jitter.
The WM8804/WM8805 ICs are known for their simplicity and flexibility in operation. They provide an easy-to-use interface and allow for the recovery of highly degraded input data. This means that even if the input signal is of poor quality, these ICs can still retrieve and process the data effectively.
By attenuating unwanted jitter, the WM8804/WM8805 ICs ensure a more stable and reliable data transfer. This has a positive impact on the overall audio quality and helps to minimize the range of problems caused by jitter. Users can expect improved clarity and accuracy in the reproduced audio signals when using these ICs.
In summary, Cirrus Logic's WM8804 and WM8805 are high-performance digital interface transceivers that comply with the S/PDIF standard. Their advanced jitter attenuating PLL allows for the recovery of degraded input data and reduces the impact of jitter-related issues. These ICs provide a simple and flexible solution for S/PDIF data recovery, routing, and transfer, ensuring improved audio quality and reliability.
