By adding a tracking feedback loop, it aims to reduce lock time and spurs. The design of fractional-N frequency synthesizer is based on a 180nm CMOS technology with 1.8V supply voltage, with the output frequency range of 699MHz-960MHz …

Phase-locked loop - Wikipedia

WebThe synthesizer works in a phase-locked loop (PLL), where a phase/frequency detector (PFD) compares a fed back frequency with a divided-down version of the reference frequency (Figure 1). The PFD’s output current pulses are filtered and integrated to generate a voltage. This voltage drives an external voltage-controlled oscillator (VCO) to ... WebThe Digital lock detect circuit uses a set window of 15nsec pulse width to determine the lock status of the PLL. When CLKIN of the DLD circuit has a pulse width of less than 15nsec for 5 consecutive cycles, the DLD circuit indicates that the PLL is locked. Once the DLD circuit indicates lock, it now looks for a loss of lock. WebThe output of U705D (FLAG) i s connected to J3-13C for external monitoring of the Synthesizer Module.
