Overview This user’s guide describes the operation of the Skyworks Solutions Si4836-DEMO board rev1.1, Nov 20, 2012. The Skyworks Solutions Si4836-DEMO board is designed with the 16-pin SOIC packaged Si4836 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 analog display AM/FM/SW radio design. The Si4836-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. 2 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.1 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • October 6, 2021 Si4836-DEMO 3.

Operation S4836-DEMO board, a complete analog tune and analog display radio, is very easy to operate: 1. Switch the SW Wideband/Narrow-band selector J7 to the desired SW Wideband or Narrow-band. 2. Switch the tuner VDD connector J10 to the desired VABT or VCC. 3. Switch the bass/treble function enable/disable selector J8 to the desired Disable or Enable. 4. Put two AAA batteries into the battery compartment. 5. Switch the power switch S1 to the ON position. The board will power up to a radio band according to the position of the band switch. 6. Change the band switch S2 to the desired band. 7. Rotate the tuning wheel VR1 and find the desired frequency. 8. Rotate the volume control wheel VR2 to get a comfortable volume. Note: For FM listening, the earphone cable must be connected to the board when J2 is set to "HP ANT" or an external antenna must be connected to the BNC connector when J2 is set to "BNC”. For AM listening, the ferrite antenna must be connected to the board and the J3 is set to "Ferrite" before Turning on the radio or band switching to AM.
