The Motorola MC34250 is a fully integrated partial response maximum

likelihood disk drive read/write channel for use in zoned recording

applications. This device integrates the AGC, active filter, 7 tap equalizer,

Viterbi detector, frequency synthesizer, servo demodulator, 8/9 rate (0,4/4)

Encoder/Decoder with write precompensation and power management in a

single 64 pin 10 mm x 10 mm TQFP package.
