Gowin SPDIF RX
Introduction
SPDIF (Sony/Philips Digital Interface Format) is a kind of digital audio transmission interface. It usually outputs by using optical fiber and coaxial line. The audio signal can be output to decoder to maintain high fidelity, and it is widely used in DTS (Digital Theatre System).
In order to better serve FPGA users, reduce the difficulty of system development and improve the speed of product development, a general SPDIF receiver controller with low power is designed to realize the function of SPDIF protocol and BMC encoding.
Gowin SPDIF receiver IP can be applied to Gowin all FPGA products by using Gowin software.
Features
- The input working clock rate of the controller shall not be less than 512Fs (FS is the audio sampling rate);
- The data and clock is recovered by asynchronous sampling data with high speed clock；
- SPDIF recovery clock is an eighth of the input working clock of the controller;
- Supports 8KHz~192Khz sample rate;
- Supports bit width of 16bit~24bit;
- Supports IEC60958 (SPDIF) and AES3 PCM data transmission;
- Locked time not greater than 1Fs;
- Lower power consumption;
- Can be synthesized.
