摘要

描述了一种采用混合信号0.8 /spl mu/m BiCMOS工艺的PRML(部分响应最大似然)通道芯片，用于硬盘驱动器(HDD)应用。该芯片仅使用5个外部组件即可完成完整的写入、读取和伺服功能，数据速率高达120 Mb/秒。正常情况下，整机功耗小于800mw。片上电路包括ADC、VGA、FIR滤波器、Viterbi解码器、两个锁相环等。

A single chip HDD PRML channel

A PRML (Partial Response Maximum Likelihood) channel chip employing a mixed-signal 0.8 /spl mu/m BiCMOS process for hard disk drive (HDD) applications is described. This chip performs the complete write, read, and servo functions using only five external components with a data rate of up to 120 Mb/sec. Under normal operating conditions the power dissipation is less than 800 mW. The on-chip circuitry includes ADC, VGA, FIR filter, Viterbi decoder, two PLL's, etc.
