Abstract

The detection of servo information in hard disk drive read channels has traditionally been implemented with analog circuits and converted with an off-chip analog-to-digital converter (ADC). The benefits of digital servo detection include system cost savings through the elimination of the off-chip ADC, reduced development time, repeatability, testability, and ease of future integration. The full digital PRML chip is described.

一个130 Mb/s的PRML读/写通道与数字伺服检测

硬盘驱动器读通道中伺服信息的检测传统上是通过模拟电路实现的，并通过片外模数转换器(ADC)进行转换。数字伺服检测的好处包括通过消除片外ADC来节省系统成本，减少开发时间，可重复性，可测试性以及易于未来集成。介绍了全数字PRML芯片。
