Abstract :
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.
