15. The residue logic determines the phase correction that must be made in each 10 ys frame to cancel the fractional phase error The residue logic drives the residue generator which produces the fractional phase error correction signal that is injected into the loop amplifier By careful alignment of the residue generator the synthesizer sidebands can be suppressed better than 50 dB below the fundamental frequency output level The N counter consists of a VCO prescaler which typically divides the VCO output frequency by 2 The prescaler also contains a pulse skipper circuit that makes the 2 circuit skip one extra clock pulse each time a skip command is given This effectively turns the prescaler into a 3 circuit during a skip command The output of the VCO prescaler drives the VCO divider The combination of the VCO divider and the VCO prescaler is capable of dividing by any integer number between 400 and 700 For example to divide by 437 the VCO divider counts 430 times and the VCO prescaler skips 7 extra VCO clocks during the count sequence yielding a total count of 437 The phase register accepts 4 bit binary coded decimal BCD frequency program data from the frequency programmer 8 decades of BCD data are transferred serially on a decade by decade basis every 10 ys All timing signals needed by the synthesizer are produced by the timing generator circuit The timing generator controls the transfer of frequency data to the phase regis

17. jumps in frequency such that the VCO remains steady at the average frequency and does not follow the loop back and forth between the two programmed frequencies However to reduce the sidebands to an acceptable level 50 dBc requires smoothing slowing the loop response to such an extent that the synthesizer would no longer be suitable for sweeps used in Chirpsounder applications These sidebands may be canceled however by using a fast loop and a fractional phase correction circuit operating in conjunction with the N Note that the average frequency of the VCO is correct Therefore the average value or dc component of the VCO control voltage from the loop amplifier is correct The undesired 1 kHz sidebands are produced by the sudden phase errors generated when the N counter jumps between the two programmed integer divide numbers This produces a small momentary change in the VCO control voltage which modulates the VCO frequency resulting in sidebands The fractional phase correction circuit cancels the VCO modulation by injecting a compensating phase error correction signal into the loop amplifier to counteract the effect of the phase error jump when the N skips from one divide ratio to 4 3 0040 8174 15001 8174 HF Monitor Receiver another The phase register keeps track of when to skip the N from one divide ratio to the next and simultaneously programs the residue logic of the fractional phase correction circuits
