PORTABLE CONSUMER CODEC
LOW-POWER, HIGH-FIDELITY INTEGRATED CODEC
DESCRIPTION
The TSCS42xx is a low-power, high-fidelity integrated CODEC
with 32 bit stereo playback stereo record functionality. In addition
to a high-fidelity low-power CODEC, the device integrates the true
cap-less headphone amplifier.
The digital audio data ports work in both master or slave modes
and supports all common Linear PCM delivery formats (I2S / LJ /
RJ / TDM) as well as direct Bluetooth® PCM mode.
Beyond high-fidelity for portable systems, the device offers an
enriched “audio presence” through built-in audio output
processing DSP engine (AOP) which is easily tunable by the
designer using the Windows®-based Tempo ASC GUI.
TARGET APPLICATIONS
