Realtek PDF datasheet ALC203 for free download

Designed for the following chipset:
- ALC203
- ALC203-LF


The ALC203 AC'97 codec is a 20-bit DAC and 18-bit ADC full duplex AC'97 2.3 compatible stereo audio codec designed for PC multimedia systems, including host/soft audio and AMR/CNR based designs. The ALC203 incorporates proprietary converter technology to achieve a high SNR, greater than 100 dB, sensing logic for device reporting, and Universal Audio Jack® to improve user experience.

The ALC203 supports multiple CODEC extensions with independent variable sampling rates and built-in 3D effects. The ALC203 CODEC provides two pairs of stereo outputs with independent volume controls, a mono output, and multiple stereo and mono inputs, along with flexible mixing, gain and mute functions to provide a complete integrated audio solution for PCs. The circuitry of the ALC203 codec operates from a +3.3V digital power and +5V analog power supply with EAPD (External Amplifier Power Down) control for use in notebook and PC applications. An integrated 14.318M to 24.576MHz PLL generate required clock to eliminate the need for external crystal. Built in PCBEEP generator to save buzzer on board.

The ALC203 integrates a 50mW/20Ω headset audio amplifier into the codec, saving BOM costs. The ALC203 also supports the SPDIF out function, compliant with AC'97 2.3, which offers easy connection of PCs to consumer electronic products, such as AC3 decoder/speaker and mini disk devices. The ALC203 codec supports host/soft audio from Intel ICHx chipsets as well as audio controller based VIA/SIS/ALI/AMD/nVIDIA/ATI chipsets.

Bundled Windows series drivers (WinXP/ME/2000/98/NT), EAX/Direct Sound 3D/I3DL2/A3D compatible sound effect utilities (supporting Karaoke, 26-types of environment sound emulation, 10-band equalizer), HRTF 3D positional audio and Sensaura™ 3D (optional) provide an excellent entertainment package and game experience for PC users.
