PHASE REGISTER, R1
With the control bits (Bits[2:0]) of Register R1 set to 001, the
on-chip phase register is programmed. Figure 18 shows the
input data format for programming this register.
12-Bit Phase Value
These 12 bits control what is loaded as the phase word. The
word must be less than the MOD value programmed in the
MOD/R register (R2). The word is used to program the RF
output phase from 0° to 360° with a resolution of 360°/MOD.
See the Phase Resync section for more information. In most
applications, the phase relationship between the RF signal and
the reference is not important. In such applications, the phase
value can be used to optimize the fractional and subfractional
Optimization section for more information.
If neither the phase resync nor the spurious optimization
functions are being used, it is recommended that the phase
value be set to 1.
