SINGLE/DOUBLE DENSITY
FLOPPY DISK CONTROLLER'
OESCRI PTION The J.1PD765 is an LSI Floppy Disk Controller (FDC) Chip, which contains the circuitry and control
functions for interfacing a processor to 4 Floppy Disk Drives, It is capable of supporting either
IBM 3740 single density format (FM), or IBM System 34 Double Density format (MFM) including
double sided recording. The J.1PD765 provides control signals which simplify the design of an
external phase locked loop, and write precompensation circuit |
