SPDIF TRANSMITTER
6.1 OVERVIEW OF SPDIF TRANSMITTER
SPDIF transmitter is based on IEC60958. This chapter describes a serial, un-directional, self-clocking interface to
interconnect digital audio equipment in consumer and professional applications. If you use a consumer digital
processing environment in SPDIF standard, the SPDIF interface is primarily intended to carry stereophonic
programs, with a resolution of up to 20 bits per sample, an extension to 24 bits per sample being possible. If you
use SPDIF in a broadcasting studio environment, the interface is primarily intended to carry monophonic or
stereophonic programs, at a 48 kHz sampling frequency and with a resolution of up to 24 bits per sample; it can
carry one or two signals sampled at 32 kHz.
In both cases, the clock references and auxiliary information are transmitted with the program. Provision in
IEC60958 is made to allow the interface to carry software related data.
6.2 KEY FEATURES OF SPDIF TRANSMITTER
• SPDIFOUT module only supports the consumer application in S5PC110
• Supports linear PCM up to 24-bit per sample
• Supports Non-linear PCM formats such as AC3, MPEG1 and MPEG2
• 2 x 24-bit buffers which is alternately filled with data
