DESCRIPTION

The STA003T is a fully integrated high flexibility MPEG Layer III Audio Decoder, capable of decoding Layer III compressed elementary streams, as specified in MPEG 1 and MPEG 2 ISO standards. The device decodes also elementary streams compressed by using low sampling rates, as specified by MPEG 2.5.

■ SINGLE CHIP MPEG2 LAYER 3 DECODER SUPPORTING:

- All features specified for Layer III in ISO/IEC 11172-3 (MPEG 1 Audio) except 44.1KHz Audio

- All features specified for Layer III 2 channels in ISO/IEC13818-3.2 (MPEG 2 Audio) except 22.05KHz Audio

- Lower sampling frequencies syntax extension, (not specified by ISO) called MPEG 2.5 except 11.025KHz Audio

■ DECODES LAYER III STEREO CHANNELS, DUAL CHANNEL, SINGLE CHANNEL (MONO)

■ SUPPORTING THE MPEG 1 & 2 SAMPLING FREQUENCIES AND THE EXTENSION TO MPEG 2.5: 48, 32, 24, 16, 12, 8 KHz
