STA304A - DIGITAL AUDIO PROCESSOR

General Description

leThe STA304A Digital Audio Processor is a single ochip device implementing end to end digital solution sfor audio application.

Key Features

  • The selection of the operating mode is done via a specific bit in a Vendor Reserved register (see bit 0: AC97_FC_mode in the CRA register, address 5Ah). The 'Full Compliant' mode is compliant with rev. 2.1 of AC`97 link specifications. This link can provide up to 6 input audio channels with sampling frequency of 44.1, 48, 88.2, 96 kHz, and the related controls. In the IIS/SPDIF mode, a stereo S/PDIF and a 4 channels three-wires programmable serial input interface work in mutually exclusive.
