Full support to 3rd generation DVD–ROM drive
Chip set for the 3rd generation DVD–ROM
■Overview
We have developed the chip set dedicated for DVD–ROM application as the 3rd generation.
Using this chip set,you can make easily[4×]speed DVD–ROM drive and[24×]speed CD–ROM drive.
■Feature
●High–speed playback up to[4×]speed for DVD–ROM drive and[24×]speed CD–ROM drive.
●Able to playback various disks such as DVD and CD.
●W ith a high–performance 32bit micro contoroller and 4Mbit DRAM,many types of optical disks like D VD,D VD–
ROM,CD–ROM,CD–audio can be handled.(MN103007B)
●All of servo function of the optical discs are integrated into the servo DSP.(MN67703)
●1 chip integration of DVD and CD analog function.(AN8701FHQ)
■Application
●DVD–ROM drive
●DVD player
●Car navigation
