DATASHEET Tempo Semiconductor, Inc. PORTABLE CONSUMER CODEC TSCS42xx LOW-POWER, HIGH-FIDELITY INTEGRATED CODEC DESCRIPTION FEATURES The TSCS42xx is a low-power, high-fidelity integrated CODEC High-Fidelity CODEC with 32 bit stereo playback stereo record functionality. In addition Stereo 32-bit DACs with 124dB SNR to a high-fidelity low-power CODEC, the device integrates the true Stereo 32-bit ADCs with 90dB SNR cap-less headphone amplifier. Supports Sample Rates from 8kHz up to 96kHz The digital audio data ports work in both master or slave modes Audio Output Processing DSP Engine and supports all common Linear PCM delivery formats (I2S / LJ / 3D Stereo Enhancement PCM mode. RJ / TDM) as well as direct Bluetooth 12-band Parametric Equalizers available per channel Wideband Dynamic Range Compressor Beyond high-fidelity for portable systems, the device offers an Pro-Style Multi-band Compressor / Limiter / Expander enriched audio presence through built-in audio output Psychoacoustic Bass Enhancement processing DSP engine (AOP) which is easily tunable by the Compressed Audio High-Frequency Restoration designer using the Windows -based Tempo ASC GUI.
