Description

The X1228S14IZ-4.5A pin is the input of an inverting amplifier. An external 32.768kHz quartz crystal is used with the X1228 to supply a timebase for the real time clock. The recommended crystal is a Citizen CFS206-32.768KDZF. Internal compensation circuitry is included to form a complete oscillator circuit. Care should be taken in the placement of the crystal and the layout of the circuit. Plenty of ground plane around the device and short traces to X1228S14IZ-4.5A are highly recommended. See Application section for more recommendations.
