Set to recommended value.
Fractional-N PLL Mode Enable. Set 1 to enable the fractional-N PLL or set 0 to enable the
integer-N PLL.
Set to recommended value.
Set to recommended value.
Lock-Detect Output Internal Pullup Resistor Enable. Set to 1 to enable internal 30kΩ pullup
resistor or set to 0 to disable the resistor. Only available when lock-detect, open-drain output
is selected (A3:A0 = 0010, D12 = 1).
Set to recommended value.
Lock-Detect Output Enable. Set to 1 to enable the lock-detect output or set to 0 to disable the
output. The output is high impedance when disabled.
Set to recommended value.
Reference Frequency Divider Ratio to PLL. Set to 0 to divide by 1. Set to 1 to divide by 2.
Set to recommended value.
Set to recommended value.
Lock-Detector Output Select. Set to 1 for CMOS Output. Set to 0 for open-drain output. Bit D9
in register (A3:A0 = 0101) enables or disables an internal 30kΩ pullup resistor in open-drain
output mode.
Set to recommended value.
Set to recommended value.
6 LSBs of 20-Bit Fractional Portion of Main Divider
8-Bit Integer Portion of Main Divider. Programmable from 64 to 255.
