ABSTRACT: A fully integrated partial response maximum likelihood (PRML)
read/write IC with analog adaptive equalization operates up to 200
MSample/s. The chip implements both matched spectral null (MSN) trellis
and standard PR4 Viterbi detectors in the digital domain as well as
digital servo. The device is integrated in a mature 0.7-μm BiCMOS
technology, has a die size of 54 mm<sup>2</sup>, and dissipates 2 W with
MSN code or 1.5 W with PR4 code at 4.5-V supply and 200 MSample/s
