1. Introduction
1.1 Features
The SPDIF Output (SPDO) block generates a 1-bit high-speed serial data stream.
The primary application is to generate SPDIF (Sony/Philips Digital Interface) data for
use by external audio equipment.
The SPDIF output has the following features:
Remark: IEC-61937 is a generic specification for transmitting non PCM data with an
IEC-60958 transport.It supports AC3, PTS, MPEG1 Layer3 (MP3). MPEG 2 BC,
MPEG 2 AAC and others.
It is possible to use the SPDO signal as a general purpose high-speed data stream.
Potential applications include use as a high-speed UART or high speed serial data
channel. In this case, the features include:
