The S/PDIF or SPDIF interface, which stands for Sony and Philips Digital Interconnect Format, transports digital audio in a compressed form between audio equipment and home theater systems.
Coaxial or fiber optic cables can be used by the S/PDIF interface to deliver audio. DVD and CD players frequently use this interface to connect to a home theater system for Dolby Digital or DTS surround sound.
This port is also found on high-end computers and sound cards. An illustration of how the SPDIF connector can appear on a computer motherboard is shown in the first image.
SPDIF transceivers can expedite time to market in both software-controlled and hardware-controlled systems. A PLL with a jitter rejection frequency of 100 Hz and an intrinsic jitter period of 50 ps is built into the transceiver’s design.
S/PDIF transceivers have traditionally only been able to reduce jitter above 10 kHz and have no effect on the medium and low frequencies, which have the greatest impact on audio quality.
The Global SPDIF transceivers market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Cirrus Logic, Inc.’s WM8805 is a high-performance consumer mode S/PDIF transceiver that supports one transmitted channel in addition to eight receiving channels.
To provide low jitter recovery of S/PDIF supplied main clocks, a crystal derived or externally provided high quality main clock is required.
A high drive clock output is provided by a dedicated CLKOUT pin. The gadget can be used to simply clean up (de-jitter) the received digital audio signals thanks to a pass through option. The device can be utilized in standalone hardware control modes or software control modes.
Edinburgh, UK The WM8804 and WM8805 audio transceivers from Wolfson Microelectronics address the difficulties of S/PDIF audio data transport at an affordable price in LCD televisions, hi-fi systems, and PC motherboards.
A PLL with an intrinsic jitter period of 50 ps and a jitter rejection frequency of 100 Hz is an essential component of the transceiver’s architecture. The audio system receives very little jitter from the WM8804 and WM8805.
The low and middle frequencies, which have the biggest an impact on audio quality, are not affected by conventional S/PDIF transceivers, which can only reduce jitter above 10 kHz. The WM8804 and WM8805 are able to eliminate any undesirable distortion or issues by suppressing jitter on the audio signal at frequencies above 100 Hz.
For use with LCD TVs, DVD recorders, musical instruments, and other personal devices demanding high-performance digital audio, the has one input and one output. The WM8805, which has eight inputs and one output, is made especially for use in devices like AV and DVD receivers, as well as commercial and home recording systems, where digital audio channel switching is required.
The PLL’s ability to reduce the number of components in the system as a whole is another advantage. The PLL can be used to create clock signals from crystals and, in the absence of an external filter, can function as the audio system’s master timing source. The WM8804 and WM8805, which include a special “with flags” mode, are fully compliant with the IEC60958-3 standard for S/PDIF. You can extract status and error information.
For usage in LCD TVs, DVD recorders, musical instruments, and other personal gadgets demanding high-performance digital audio, the WM8804 offers one input and one output. The WM8805, which has eight inputs and one output, is made especially for use in devices like AV and DVD receivers, as well as commercial and home recording systems, where digital audio channel switching is required.
