NOISE CHARACTERISTICS  
In-Band Phase Noise of the Charge Pump/  
Phase Frequency Detector (In-Band  
Means Within the LBW of the PLL)  
The PLL in-band phase noise floor is estimated by  
measuring the in-band phase noise at the output of  
the VCO and subtracting 20 log(N) (where N is the value  
of the N divider)

dBc/Hz  
dBc/Hz Reference slew rate > 0.5 V/ns; FOM + 10 log(fPFD) is an  
approximation of the PFD/CP in-band phase noise (in  
the flat region) inside the PLL loop bandwidth; when  
running closed-loop, the phase noise, as observed at  
the VCO output, is increased by 20 log(N); PLL figure of  
merit decreases with decreasing slew rate; see Figure 11  
PLL DIGITAL LOCK DETECT WINDOW2  
Lock Threshold (Coincidence of Edges)  
Signal available at the LD, STATUS, and REFMON pins  
when selected by appropriate register settings; lock  
detect window settings can be varied by changing the  
CPRSET resistor  
Selected by 0x017[1:0] and 0x018[4] (this is the threshold  
to go from unlock to lock)

REFIN  
The REFIN and  
self-bias points are offset slightly to avoid chatter on an open input condition.  
2 For reliable operation of the digital lock detect, the period of the PFD frequency must be greater than the unlock-after-lock time.
