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.
