4.1 AC ’97 Sound Controller
The JFLEX-Multimedia uses a Realtek ALC650 sound codec. The ALC650 is an
18-bit, full duplex AC’97 2.2 compatible stereo audio CODEC designed for PC
multimedia systems, including host/soft audio and AMR/CNR based designs. The
ALC650 incorporates proprietary converter technology to achieve a high SNR,
greater than 90 dB.
The ALC650 also supports an AC’97 2.2 compliant S/PDIF out function which
allows easy connection from the PC to consumer electronic products, such as
AC3 decoder/speaker and mini disk.
All major operating systems support the interface.
