HD153068RTF

110-Mbps PRML Data Channel Processor

ADE-207-252 (Z)

Preliminary

1st Edition

February 1998

Description

The HD153068RTF is a fully integrated single-chip data channel processor for high performance magnetic

disk drives. Functions include automatic gain control (AGC), programmable active filter, A/D converter,

FIR transversal filter, Viterbi qualifier, 8/9 ENDEC, data synchronizer, 4-burst servo demodulator, write

PLL, and programmable write precompensation. The HD153068RTF is capable of 40Mbits/s to 110Mbits/s

data rates and supports single zone and Multi Zone Recording.

The HD153068RTF is fabricated in HITACHI 0.7µm Hi-BiCMOS process technology which provides

high performance with low power consumption. Built-in programmable power management reduces power

dissipation to 10 mW when in sleep mode.
