REGISTER 3
Control Bits
With Bits[C3:C1] set to 0, 1, 1, Register 3 is programmed.
Figure 22 shows the input data format for programming
this register.
Antibacklash Pulse Width
Setting DB22 to 0 sets the PFD antibacklash pulse width to 6 ns.
This is the recommended mode for fractional-N use. By setting
this bit to 1, the 3 ns pulse width is used and results in a phase
noise and spur improvement in integer-N operation. For
fractional-N mode it is not recommended to use this smaller
setting.
Charge Cancellation Mode Pulse Width
Setting DB21 to 1 enables charge pump charge cancellation.
This has the effect of reducing PFD spurs in integer-N mode.
In fractional-N mode, this bit should not be used. This results
in a phase noise and fractional spur improvement.
Cycle Slip Reduction (CSR) Enable
Setting DB18 to 1 enables cycle slip reduction. This is a method
for improving lock times. Note that the signal at the phase fre-
quency detector (PFD) must have a 50% duty cycle for cycle slip
reduction to work. The charge pump current setting must also
be set to a minimum. See the Cycle Slip Reduction for Faster
Lock Times section for more information.
Clock Divider Mode
Bits[DB16:DB15] must be set to 1, 0 to activate phase resync or
0, 1 to activate fast lock. Setting Bits[DB16:DB15] to 0, 0
disables the clock divider. See Figure 22.
12-Bit Clock Divider Value
The 12-bit clock divider value sets the timeout counter for
activation of phase resync. See the Phase Resync section for
more information. It also sets the timeout counter for fast lock.

REGISTER 4
Control Bits
With Bits[C3: C1] set to 1, 0, 0, Register 4 is programmed.
Figure 23 shows the input data format for programming this
register.
This register is reserved and has to be programmed with the
values as shown in Figure 23. Bits[DB31:DB24] and [DB22:DB3]
must be programmed to 0, while Bit DB23 must be set to 1.
REGISTER 5
Control Bits
With Bits[C3:C1] set to 1, 0, 1, Register 5 is programmed.
Figure 24 shows the input data form for programming this
register.
Lock Detect PIN Operation
Bits[DB23:DB22] set the operation of the lock detect pin (see
INITIALIZATION SEQUENCE

initial power up of the ADF4151 after the correct application
of voltages to the supply pins:
1. Register 5
2. Register 4
3. Register 3
4. Register 2
5. Register 1
6. Register 0
