UTC 6610
FREQUENCY AND CLOCK


DISPLAY DRIVER
The UTC 6610 is a frequency and clock display driver
used for displaying FM/AM radio frequency or a 12 hour
alarm clock. By using CMOS technology, it consumes very
low power in clock display mode.
FEATURES
* FM input with pre-scalar for radio frequency up to 150
MHz
* AM input for radio frequency up to 30 MHz
* 3 common, 13 segment, 1/3 bias LCD display drivers
which supports 4 digits LCD display
* On chip oscillator for external 32.768kHz crystal
* 10.7 MHz / 70 kHz I.F. frequency offset for FM signal and
455kHz I.F. frequency offset for AM signal
* Internal real time clock in 12 hour display mode
* Selectable clock or frequency display
* 1.8V to 3.3V supply voltage
