FLOPPY DISK VFO
October 1964 Edition 1.0
The Fujitsu MB 4107 is a variable-frequency oscillator (VFO) Ie for use in floppy-disk interfaces_ It provides a complete data separation function, with a minimum of external parts and no adjustments, and can be used with a variety of disk controllers_ It locks onto the read signal from the disk drive, which normally has jitter due to rotation speed variations and peak shifting, and produces a stable read signal for the controller_ It also produces a window signal, which can be used to differentiate the clock and data pulses in the read signal.
