Description

STA027 is a fully integrated SBC codec targeting

wireless audio transmission such as DVD rear

channels wireless speakers, USB dongle, PC

wireless speakers. The device is fully controllable

through a standard I2C bus.

Compression Engine

SBC

The SBC Subband Coding engine can be used

when high quality audio is required in wireless

applications (such as Bluetooth). SBC is an audio

coding system specially designed for Bluetooth

AV applications to obtain high quality audio at

medium bit rates, and having a low computational

complexity. SBC uses 4 or 8 subbands, adaptive

bit allocation algorithm, and simple adaptive block

PCM quantizers..
