WESTERN DIGITAL c oR p o R A T oN WD1691 FLOPPY SUPPORT LOGIC (F.S.L.) FEATURES .. Direct interface to the FD179X • Eliminates external FDC Logic .. Data Separation/RCLK GENERATION .. Write Precompensation Signals • VFOE/WF Demultiplexing • Programmable Density o 8" or 5.25" Drive Compatible .. All inputs and outputs TTL Compatible ... Single +5V Supply GENERAL DESCRIPTION The WD1691 F.S.L. has been designed to minimize the external logic required to interface the 179X Family of Floppy Disk Controllers to a drive. With the use of an external VCO, the WD 1691 will generate the RCLK signal for the WD179X, while providing an adjustment pulse (PUMP) to control the VCO frequency.
