6
CP offset current polarity
Selects the polarity of the charge pump offset current of the output PLL.
0 = pump up (default).
1 = pump down.
This bit is ineffective unless Bit 3 = 1.
[5:4]
CP offset current
Controls the magnitude of the charge pump offset current of the output PLL as a
fraction of the value in Register 0x0A. Ineffective unless Bit 3 = 1.
00 = 1/2 (default).
01 = 1/4.
10 = 1/8.
11 = 1/16.
3
Enable CP offset current control
Controls functionality of Bits[6:4].
0 = the device automatically controls charge pump offset current (default).
1 = charge pump offset current defined by Bits[6:4].
2
Reserved
Enables PFD up divide-by-2 (reserved for test).
1
Reserved
Enables PFD down divide-by-2 (reserved for test).
0
Reserved
Enables feedback divide-by-2 (reserved for test).
0x0D
[7:6]
Antibacklash control
Controls the PFD antibacklash period of the output PLL.
00 = minimum (default).
01 = low.
10 = high.
11 = maximum.
These bits are ineffective unless Register 0x0B[6] = 1.

Unused.
0
Output PLL lock detector
power-down
Controls power-down of the output PLL’s lock detector.
0 = lock detector active (default).
1 = lock detector powered down.

7
Calibrate VCO
Initiates VCO calibration (this is an autoclearing bit). This bit is ineffective unless Bit 2 = 1.
6
Enable automatic level control
Enables automatic level control of the VCO.
0 = VCO level defined by Register 0x0F[7:2].
1 = the device automatically controls the VCO level (default).
[5:3]
Automatic level control
threshold
Controls the VCO threshold detector level. The default is 110. Note that the function-
ality of Bit 4 is inverted; that is, the minimum is 010, and the maximum is 101.
2
Enable SPI control of VCO
calibration
Enables functionality of Bit 7.
0 = the device automatically performs VCO calibration (default).
1 = Bit 7 controls VCO calibration.
1
Boost VCO supply
Selects VCO supply voltage.
0 = normal supply voltage (default).
1 = increase supply voltage by 100 mV.
0
Enable SPI control of VCO band
setting
Controls VCO band setting functionality.
0 = the device automatically selects the VCO band (default).
1 = VCO band defined by Register 0x10[7:1].
0x0F
[7:2]
VCO level control
Controls the VCO amplitude from minimum (00 0000) to maximum (11 1111). The
default is 10 0000. These bits are ineffective unless Register 0x0E[6] = 0.
[1:0]

Unused.
0x10
[7:1]
VCO band control
Controls the VCO frequency band from minimum (000 0000) to maximum (111 1111).
The default is 100 0000.
