Disk-Read ICs Condition and Deliver Bits at 50 Mbits/s

AD890 Provides AGC Over Wide Range of Input Amplitudes; AD891's Precise Comparators and One-Shot Pinpoint Output Signal

The AD890 Precision Wideband Channel Processing Element and AD891 Rigid-Disk Data Qualifier are a pair of application-specific integrated circuits (ASICs) designed for use between the head readback preamplifier and data decoder of high-performance disk drives. Starting with the noise-corrupted and distorted signal from the disk head, these monolithic components produce error-free digital bits at rates up to and beyond 50 megabits/second (Mbits/s). Read full article
