Figure 6-32 is a pre-dual-mode frequency-divided phase-locked frequency synthesizer composed of MC145152, used in aeronautical navigation receivers. MC3393P in the picture is a dual-mode prescaler, which works in ÷ V / (V + 1) (V = 15) mode, and its maximum operating frequency is 140 MHz. The reference oscillation frequency is 32 MHz. Now set RA2 RA1 RA0 = 001, the reference frequency division ratio can be found to be 64, and the phase discriminator operating frequency is 50 kHz. Control N = 114 ~ 127, A = 0 ~ 14, you can synthesize the required frequency band 86000 ~ 95950 MHz.
