摘要

最近的磁盘驱动器要求高传输速率和记录密度。PRML信令现在在数字读/写信道中很流行。该PRML芯片的最大数据速率为150mb /s，功率为1550 mW，包括所有基本功能，如伺服解调和磁盘驱动器的写入预补偿，优化电路尺寸。该芯片采用0.7 /spl mu/m双聚双金属BICMOS制造，适用于低功耗器件，封装在100引脚四平面封装中，芯片尺寸约为7 mm/sup /。这个芯片有一个5v电源。

A 150 Mb/s PRML chip for magnetic disk drives

Recent magnetic disk drives require high transfer rates and recording densities. PRML signaling is now prevalent in digital read/write channels. This PRML chip operates at a maximum data rate of 150 Mb/s with 1550 mW and includes all basic functions such as servo demodulation and write pre-compensation for magnetic disk drives with optimized circuit size. The chip is fabricated in 0.7 /spl mu/m double-poly double-metal BICMOS suitable for low-power devices and is packed in a 100-pin quad flat package with a die approximately 7 mm/sup 2/. This chip has a single 5 V power supply.
