Proteus project +asm
Frequency synthesizer with AT89C52 and LC72131 (PLL)  10-40MHz  steps 1MHz -100-50-25-10-5-1KHz
serial connection with PC
Software in Labview
autoincrement
TA 8176 used for VCO
real frequency of vco is 90-120MHz
 -80MHz(from quartz osc)=10-40MHz on LCD

made at school for final exam
if you have questions please ask

>I don't know but you can obtein this range mixing and filtering for example 4-5MHz from PLL to an osc with quartz of 4MHz rezult 0-1000Khz with step 1KHz and after dividing with 1000 you obtain 0-1000Hz with step of 1Hz in this way you have high stability

or you can try with http://pdf1.alldatasheet.com/datasheet-pdf/view/118258/ETC/NE565.html
