2. Overview

This manual describes the operation of the Skyworks Solutions Si4822/26-DEMO Board Rev1.0, October 24,

2011. The Skyworks Solutions Si4822/26-DEMO Board is designed with the 24-pin SSOP-packaged Si4822/26

chip, the revolutionary single chip AM/FM/SW receiver that integrates everything from antenna input to audio

output and allows use of common and economical potentiometers to do the frequency tuning. It provides a

complete portable analog tune digital display AM/FM/SW radio design. The LCD displays the tuning information.

The Si4822/26-DEMO is designed with 1-layer PCB, allowing the lowest cost without sacrificing the RF

performance. The demo board works with two AAA batteries and working voltage down to 2.0 V.

4. Operation

The Si4822/26-DEMO board, a complete analog tune and digital display radio, provides two major modes of

operation: Time mode and FM/AM/SW Radio mode.

4.1. Time Mode

Place two AAA batteries into the battery compartment. The board will automatically enter Time mode and display

the time.

The demo board display in Time mode is illustrated in Figure 1.

4.1.1. Time Setting

The time default value is 00:00 and can be set to the correct time manually when needed.

1. In Time mode, press the BASS/TMR button to enter the setting menu. The default is to set the minute item

first. Press this button again to select the hour item. The selected item flashes.

2. While the selected item is flashing, press the DOWN/VOL- and UP/VOL+ button to set the desired time.

3. When you have finished setting the time, press BASS/TMR button to quit the setting menu. The MCU will

automatically quit the setting menu if there is no operation within 2 seconds.

4.1.2. Alarm Setting

1. In Time mode, press the TREBLE/AL button to enable or disable the alarm function and to enter the setting

menu automatically when the alarm is enabled. Once you have entered the setting menu, the default is to

set the minute item first. Pressing this button again will select the hour item. The selected item flashes.

2. While the selected item is flashing, press the DOWN/VOL- and UP/VOL+ button to set the desired time.

3. When you have finished the alarm setting, press TREBLE/AL button to quit the set menu. The MCU will

automatically quit the setting menu if there is no operation within 2 seconds.

4. If the alarm is enabled and the alarm setting time is matched, the radio will be automatically turned on after

the buzzer sounds for 5 seconds.

5. The radio will be turned off and the demo board will go into sleep mode automatically if there is no

operation on the push buttons within 15 minutes; if there is any operation on the push buttons, the auto-

sleep function will be disabled. The radio keeps working throughout this time.

4.2. FM/AM/SW Radio Mode

In time mode, the device will enter FM/AM/SW mode after a long press (hold time > 1s) of the POWER/BAND

button or when the alarm time is reached. The LCD displays the following information: band indicator, band

frequency indicator, and sleep indicator in case the radio is automatically turned on by the alarm.

The demo board display in FM/AM/SW mode is illustrated in Figure 3.

Figure 3. LCD Display in FM Radio Mode

The demo board provides two methods to select the radio band: one is to use the slide switch (S2), the other is to

use the POWER/BAND push button. S14 determines which method is in use.

The demo board also provides two methods to set the band property: one is to use tuner default values, the other

is to use the keypad to reconfigure band property value via the MCU. S13 determines which method is in use. If

you use the tuner default values, the band property is fixed and cannot be re-configured. Refer to Section "4.2.1.

MCU Setting Band Property” for the operation details for setting the band property using the keypad.

To operate the demo board, follow these procedures:

1. According to the desired radio band selection method, set S14 to use the slide switch or push button.

2. According to the desired radio band property, set S13 to use tuner default values or reconfigure the band

property.

3. Hold the POWER/BAND push button (hold time > 1s) or when the alarm time is reached, the device will

enter FM/AM/SW mode.

4. Use slide switch S2 or press the POWER/BAND push button to select the desired band.

5. Refer to section "4.2.1. MCU Setting Band Property” or section "4.2.2. MCU Setting Radio Working Mode”

to reconfigure the band property or radio working mode if necessary.

6. Rotate the tuning wheel and find the desired radio station with the help of the LCD display and/or tuning

indicator D1.

7. Rotate the volume control wheel VR2 and/or press the DOWN/VOL- or UP/VOL+ button to get a

comfortable volume. Press the BASS/TMR or TREBLE/AL button to get the desired bass/treble level.

Notes:

For FM listening, the earphone cable must be connected to the board when S12 is set to HP ANT or an

external antenna must be connected to the BNC connector when S12 is set to BNC.

For AM listening, the ferrite antenna must be connected to the board and the S11 is set to Ferrite before

turning on the radio or switching the band to AM.
