Abstract
A PR4 read/write IC operating at 50-200 Mb/s while consuming 0.85 W is implemented in 0.5 mu m BICMOS technology, The device integrates all of the read/write functions and, in addition, provides a servo demodul ator and power management in a single 64-pin TQFP package, PR4 equaliz ation is achieved via a continuous time filter and a 7-tap continuous time transversal equalizer using signed-signed least mean square adapt ation.
