S7G2 Datasheet

1. Overview

Data Operation Circuit (DOC)

The Data Operation Circuit (DOC) compares, adds, and subtracts 16-bit data. See section 52,

Data Operation Circuit (DOC) in Userʼs Manual.

Sampling Rate Converter (SRC)

The Sampling Rate Converter (SRC) converts the sampling rate of data produced by various

audio decoders, such as the WMA, MP3, and AAC. Both 16-bit stereo and monaural data are

supported. See section 42, Sampling Rate Converter (SRC) in Userʼs Manual.
