Being 'digitaly challanged", I'm having difficulty adding a simple "fixed frequency" memory feature to the frequency command function on AD synthesizer ICs. I'm looking to operate the synthesizer at ONE fixed frequency upon turn on and to repeat the frequency when turned off and then on again. This is for a fixed frequency LO application that cannot use microcontroller or PC interface for frequency control. Is there a simple way to accomplish this? Would a serial EEPROM do this?
Your help is appreciated...Bill
