Abstract :
A fully-integrated PRML read/write IC with digital adaptive FIR operating up to 450 Mbit/s is presented, The chip implements an EPR4 Viterbi detector as well as a digital servo. The device is integrated in a 0.35 μm BiCMOS technology, has a die size of 11.44 mm2 (step and repeat) and dissipates 1.3 W (in read mode) at 450 Mbit/s
