The e1217X is an integrated circuit in CMOS SiliconGate Technology for analog watches. It consists of a32-kHz oscillator, frequency dividers down to 1/64 Hz,output pulse formers and push-pull motor drivers. Fortuning of the crystal, integrated capacitors are provided(selectable mask option). Low current consumption andhigh oscillator stability are enabled by an on-chip voltageregulator.
