Abstract

In FM radio receivers many frequency instabilities are found in the form of interference from other transmitter radio frequencies. This requires a frequency locking system that can lock the frequency of the relationship between the reference frequency and the frequency wave generated by VCO. The locking system is the Phase Locked Loop system. The Phase Locked loop system requires a divider frequency circuit that uses IC TC9122, input the IC frequency divider will experience a division process that is controlled by a DIP Switch that has been calculated based on the desired frequency to be locked. With this background, it is necessary to create Frequency Dividers for Phase Locked Loops Based on IC TC9122 ", because they see how important PLL is in the radio reception system as a frequency stabilizer. The results of this tool get stability, if the DIP Switch value is calculated based on multiplication of 8 stable prescaler frequencies. To obtain the output frequency stability, the calculation refers to the output of the prescaler 8 divider.

Abstract

Radio Network already exist and it was used long time ago. Its use that the radio networks can communicate through frequency in the air, definitely it simplifies us to transmit the information to others. Along with the development of technology nowadays, the radio network has been applied into several media, one of the impact of an advanced technology is the existing of transmitter for remote of a level monitoring for speaker power based microcontroller. This study used Microcontroller ATmega 8535 as the voltage level processor in which produced by the speaker to be transformed into data and utilize the RF communication media with frequency drop of 433 MHz which used to transmit data to the speaker, so it can be displayed through the computer. The result of the establishment of this device, namely pin ADC on the MicroController has read the data analog from the speaker and pin TXD on MicroController has transmit the data well. Keywords : ADC, Microcontroller, RT434A
