12-Hour System Clock IC for 1/2 Duty Fluorescent Display Tubes
FEDL9298-01
Issue Date: Jul. 11, 2005
GENERAL DESCRIPTION
The ML9298 is a 12-hour system clock IC that drives 1/2 duty fluorescent display tubes. It has a wide range of
power supply using an oscillation source of 4.194304 MHz. The ML9298 has a time adjustment function in hour,
minute and 30-minute units, and the function has two adjustment modes, 1 Push 1 ADJ and 2Hz fast forward.
Additionally, it has a brightness adjustment function for the fluorescent display tube, providing four levels of
brightness settings.
