SPDIF Controller
Our SPDIF (Sony/Philips Digital Interface) Controller IP is a core that implements the Sony/Philips Digital Interface (IEC 60958), which is an unidirectional and self-clocking interface for connecting digital audio equipment by using linear and non-linear PCM coded audio samples. The non-linear usage occurs with pass-through supported.
The IP is architected to quickly and easily integrate into any system-on-chip (SoC) thanks to the adherence to interface standards such as AMBA 2 APB and provides a convenient, cost-effective solution offering advanced configurability. High performance is yet another characteristic feature of the compact architecture offered by the Cadence Sony/Philips Digital Interface Controller IP, affecting the silicon size and increasing power saving.
