GSL100 is a highly integrated solution for portable CD music players. CD-R and CD-RW media are supported and compressed audio formats such as MP3 are decoded by the internal DSP without additional hardware support. GSL100 is a true “system-on-chip” which incorporates Sigma-Delta ADCs directly interfacing to the optical pick-up photodiodes and a CD servo unit generating motor and lens actuator signals.
GSL300 is a highly integrated solution for portable CD music players. CD-R and CD-RW media are supported and compressed audio formats such as MP3 and WMA are decoded by the internal DSP without additional hardware support. Newly emerging compressed music formats can be decoded through a simple software upgrade whilst players already with customers can be re-flashed by inserting an upgrade CD.
The Global Silicon GSL500 is a powerful system-on-chip targeted at high performance CD consumer audio systems. The GSL500 implements full rate 320kbps MP3 and WMA decoding from CD, USB and SD Card media and 128kbps MP3 stereo encoding from CDs, tuner or LineIn source.
Full rate MP3 and WMA playback is supported from all media below. Encoded MP3 files can be written to USB and SD / MMC media.
GSL800 (Flash Media Player)
The Global Silicon GSL800 system-on-chip allows the design of portable MP3 / WMA flash music players with lower system cost, increased battery life and with superior performance. The integrated power management logic supports various battery configurations including Li-Ion and single or dual AA and AAA cells. MP3 and WMA audio files can be decoded up to full 320kbps fixed and variable rates. Windows Media Video (WMV) playback will be supported later.
