Description
The e1466D is an integrated circuit in CMOS Silicon Gate Technology for analog
clocks. It consists of a 32-kHz oscillator, frequency divider, output pulse formers and
push-pull motor drivers. Integrated capacitors are mask-selectable to accomodate the
external quartz crystal. Additional capacitance can be selected through pad bonding
for trimming the oscillator frequency.
