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-/spl mu/m BiCMOS technology, has a die size of 54 mm/sup 2/, and dissipates 2 W with MSN code or 1.5 W with PR4 code at 4.5-V supply and 200 MSample/s.
