Product specification
SAA7274
GENERAL DESCRIPTION
The SAA7274 is an Audio Digital Input Circuit (ADIC) which converts digital audio signals in accordance with the
IEC/EBU standards, IEC tech. com. No. 84, secr. 50, Jan. 1987 into an equivalent binary value of data and control bits.
The output function of this device is to convert the equivalent binary value of data bits (for each channel) into a serial
digital audio signal which conforms to the I²S format.
Features
• I²S bus output
• Biphase audio signal (Satellite radio, compact disc and DAT)
