Combo hard disk controllers are highly integrated, automated single-chip drive manager and disk drive controller solutions designed for high-performance, headerless ATA drive applications.
Includes a servo block which supports both synchronous
and asynchronous servo demodulators.
For asynchronous, it provides all the necessary
timings for the read channel to recover the servo
information.
For the asynchronous servo, it has two interfaces
to receive the servo information and store it for
DSP accesses.
