AVR ATMega8 board for PLL MC145170

 


This board allow to manage a FM transmitter including a Phase Locked Loop (PLL)on a serial bus (SPI) like a MC145170. A current frequency is memorized in EEPROM to configure PLL at power up. Three auxiliairy frequencies are available for maintenance function and/or HF adjust. A local interface include 4 keys and a LCD display enable to modify transmitter parameters. This board can be completely drived from a serial link RS232 (19200 Bds,8b data,2b stop, no parity). A temperature sensor enable to control working temperature and 2 analog input are used for HF power measure (Forward and Reflected). Information about TOS protection activation is processed by this board to inform user (local and remote) on a TOS Alarm.
