Abstract
A fully integrated partial response maximum likelihood (PRML) read/wri te IC with analog adaptive equalization operates up to 200 MSample/s. The chip implements both matched spectral null (MSN) trellis and stand ard PR4 Viterbi detectors in the digital domain as well as digital ser vo, The device is integrated in a mature 0.7-mu m BiCMOS technology, h as a die size of 54 mm(2), and dissipates 2 W with MSN code or 1.5 W w ith PR4 code at 4.5-V supply and 200 MSample/s.
