RADIO FREQUENCY DISPLAY OPERATION (DTS MODE): The FM and AM local oscillator output generated from the external RF receiver enters a high gain input comparator through the FMIN and the AMIN pins respectively. The FM signal then routes through a divide-by10 dynamic pre-scalar. Depending on the state of the AM/FM-SEL pin, the FM and AM signal will be selected and enters the IF frequency offset block. Depending on the FM/AM selection, 10.7MHz/70kHz or 455kHz I.F.frequency will be subtracted or added from the input signal. LCD DISPLAY RANGE: MODE RANGE DISPLAY RANGE (ON LCD) FM H 11.00 MHz to 99.99 MHz L 11.00 MHz to 149.9 kHz AM H 500 kHz to 9999 kHz L 0.5 MHz to 29.99 MHz Note:1 When counter frequency overflow, MSB will not be displayed.

CLOCK FUNCTION: 1) The clock will be advanced in the following flow: PM 12:00 → PM 11:59 → AM 12:00 → 11:59 2) The [:] sign is the second indicator and will blink at a rate of 2Hz 3) TIME SETTING: -- Pressing the keys combination of [TIME SET] [HR SET] or [TIME SET] [MIN SET] will enter the time setting mode. -- One digit will be incremented after entering the alarm setting mode. Keep pressing the keys combination for more than 0.5 seconds will make the digit to be advanced at a rate of 2Hz. 4) ALARM TIME SETTING: -- Pressing the keys combination of [AL DISP] [HR SET] or [AL DISP] [MIN SET] will enter the alarm time setting mode. The [AL] indicator will turn on and the [:] sign will stop blinking. -- One digit will be incremented after entering the alarm setting mode. Keep pressing the keys combination UTC UNISONIC TECHNOLOGIES CO. LTD 5 QW-R502-011,A UTC 6610 CMOS for more than 0.5 seconds will make the digit to be advanced at a rate of 2Hz. 5) ALARM FUNTION: -- AL OUT output pin will output an alarm frequency of 1024Hz at 0.2 sec on and 0.2 sec off. -- AL OUT pin can be used to direct drive a piezo buzzer. -- When alarm is active, AL OUT output can be disabled by pressing the [AL-ON/OFF] key or it will turn off automatically after 3 minutes lapse. -- AL-SIG pin is an open drain output (active low). Once alarm is activated, AL-SIG can be disabled by pressing [AL-ON/OFF] key or it will turn off automatically after one hour time lapse. -- When [AL DISP] is pressed, alarm setting time will be displayed on the LCD and the [AL] indicator will be on. -- The [AL-ON/OFF] pin will toggle the [ ] indicator to turn on of off the alarm function. When the indicator is on, alarm function is on. 6) 32.768kHz crystal is used for the reference frequency. 7) After Power-on-reset (RST): -- [HR SET] and [MIN SET] keys will be disabled. -- [AL-DISP] KEY,[AL-ON/OFF] KEY AND AL-SIG output will be enabled. 3. After POWER-ON-SET(RST): -- When in clock mode, it will display and start at AM 7:00. -- When in DTS frequency mode, if CLKFREQ-SEL = High, and FMIN & AMIN pins are grounded, all LCD segments will be turned on(LCD test mode). 4.
