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. Integrated capacitors are provided (select-
able mask option) for tuning of the crystal. Low current consumption and high
oscillator stability are enabled by an on-chip voltage regulator.
