NOISE CHARACTERISTICS
In-Band Phase Noise of the Charge
Pump/Phase Frequency Detector2
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)

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 12
PLL DIGITAL LOCK DETECT WINDOW3
Signal available at the LD, STATUS, and REFMON pins
when selected by appropriate register settings; the lock
detect threshold varies linearly with the value of the
CPRSET resistor
Lock Threshold (Coincidence of Edges)
Selected by Register 0x017[1:0] and Register 0x018[4]
(this is the threshold to go from unlock to lock)
Low Range (ABP 1.3 ns, 2.9 ns)

ns
Register 0x017[1:0] = 00b, 01b,11b;
Register 0x018[4] = 1b
High Range (ABP 1.3 ns, 2.9 ns)
7.5
ns
Register 0x017[1:0] = 00b, 01b, 11b;
Register 0x018[4] = 0b
High Range (ABP 6.0 ns)
3.5
ns
Register 0x017[1:0] = 10b; Register 0x018[4] = 0b
Unlock Threshold (Hysteresis)3
Selected by Register 0x017[1:0] and Register 0x018[4] (this
is the threshold to go from lock to unlock)

Register 0x017[1:0] = 10b; Register 0x018[4] = 0b
1
The REFIN and REFIN self-bias points are offset slightly to avoid chatter on an open input condition.
2
In-band means within the LBW of the PLL.
3
For reliable operation of the digital lock detect, the period of the PFD frequency must be greater than the unlock-after-lock time.
