General Description
The e1217X is an integrated circuit in CMOS Silicon Gate Technology for analog watches. It consists of a
32-kHz oscillator, frequency dividers down to 1/64 Hz, output pulse formers and push-pull motor drivers. For tuning of the crystal, integrated capacitors are provided (selectable mask option). Low current consumption and high oscillator stability are enabled by an on-chip voltage regulator.
